Edgewater Bridge Structural Memo
Executive Summary
The Edgewater Bridge is a five-span (52’:78’:91’:78’:52’) 351-foot long, 37-foot wide concrete bridge built in 1946. The bridge’s superstructure consists of two longitudinal concrete girders that are spaced at 22 feet center-to-center and which are made composite with an 8” concrete deck. The bridge’s substructure consists of concrete columns founded on concrete pilings.
The narrow two-lane bridge is Functionally Obsolete, Structurally Deficient, and seismically vulnerable. It is also a vital link in a chain of three bridges that provide the only access to neighborhoods located along the Mukilteo Boulevard
The City of Everett tasked TranTech Engineering, LLC (TranTech) with performing a structural assessment of the bridge to obtain information regarding its structural integrity. The structural assessment has revealed that the bridge is deficient for load capacity and is seismically at risk.
An updated load rating report was prepared as part of the assessment which was based on the results of a recent special access, in-depth inspection of the bridge that was performed by TranTech staff. This report shows that the bridge is deficient for all of the rating trucks analyzed and supports the updated Deck Overall condition code reported to the bridge inventory and the resulting Sufficiency Rating of 11.71 SD.
The lowest load rating value is associated with the bridge deck, mainly due to its substandard design and existing deterioration, even under the current load-posted restrictions.
A preliminary seismic analysis of the bridge was also performed and the results show it to be vulnerable during seismic events.
Finally, the Bridge is deficient functionally with narrow substandard traffic lanes and sidewalks.
By these results and observations, it is recommended that the Edgewater Bridge be replaced. Please see Appendix C for a preliminary replacement bridge concept, Appendix D for an associated construction cost estimate, and Appendix E for an updated funding application form.

1. INTRODUCTION
The Edgewater Bridge is a five-span (52’:78’:91’:78’:52’) 351-foot long, 37-foot wide concrete bridge built in 1946. The bridge’s superstructure consists of two longitudinal concrete girders that are spaced at 22 feet center-to-center and which are made composite with an 8” concrete deck. The bridge’s substructure consists of concrete columns founded on concrete pilings. The existing bridge plans are available under the “Records/Plans” tab in the WSDOT Bridge Inspection Software.
The narrow two-lane bridge is Functionally Obsolete, Structurally Deficient, and seismically vulnerable. The Bridge is a vital link in a chain of three bridges that provide the only access to neighborhoods along the Mukilteo Boulevard; an NHS route between the cities of Everett and Mukilteo. The Mukilteo Boulevard traverse deep ravines and winds along steep hillsides. This facility is the only access to the neighborhoods along its length and serves over 6000 vehicles per day in its load-restricted condition. If any two of these three bridge were to fail during a seismic event, there would be no other access to the areas isolated by the bridge failures.
The cities of Everett and Mukilteo have struggled for years with the issues caused by the substandard and deficient bridges and the other two bridge, Maple Heights (SID 08560500) and Merrill & Ring (SID 08560600), both have projects proposed to deal with their existing deficiencies.
While the project funding requests are being submitted separately, the City of Everett intends to combine as many of the projects as possible into a Mukilteo Boulevard Bridge Replacement and Repair Program to achieve maximum efficiency and economy while solving long standing issues caused by the low structural capacity and functional obsolescence.
The City of Everett has initiated several structural assessment investigations for each of the requests for bridge funding from the WSDOT administered Local Bridge Program. The structural assessment of the Edgewater Bridge is further described in the following sections:
2. STRUCTURAL ASSESSMENT
The structural assessment performed as part of this study had a three-tier approach as detailed below:
2
2.1 Tier 1 - In-depth Bridge Inspections – The in-depth inspection of the Edgewater Bridge was performed on May 30, 2017. The focus of the inspections was the damage to the non-redundant girders along with the bridge deck and soffit. All inspections were performed utilizing an Under Bridge Inspection Truck (UBIT) hired by the City of Everett to provide access to critical structural elements of concern.
The deck deterioration is concealed by an asphalt wearing surface overlay. All soffit deterioration was recorded with special attention being paid to the cracking, spalling, and the section loss of deck reinforcing steel as evident by rusty leaching and the spalling of concrete cover. It is of note that the inspection was performed on a rainy day which highlighted the full depth leakage of water and contaminants through the deck.
Another area of concern and inspection focus were the two longitudinal concrete girders. Special attention was paid to high shear zones as the shear reinforcement details of the original design appear deficient. Full-depth shear cracks were identified and recorded.
Based on these in-depth inspections a new Inspections Report was entered in the WSDOT Bridgeworks software. Please see Appendix A for the Current Inspection Report.
3
2.2 Load Rating Analysis – A new load rating report was prepared per current LFR Method guidelines provided by WSDOT and FHWA using the in-depth inspection information. Please see Appendix B for the Summary Sheet of this Updated Load Rating. The substandard deck design coupled with the deck deterioration has resulted in additional capacity loss. This loss of capacity is also a calculated support for the reduction of the NBI deck code from a 6 (Fair Condition) to a 4 (Poor Condition) in accordance with the condition description provided by the WSDOT Bridge Inspection Manual (BIM).
The Edgewater Bridge is currently load posted at levels required by the previous load rating recommendations and the City has installed signs in advanced of the bridges warning of load posted bridges ahead. These warnings are due to the restricted access into the area as well as the lack of room for large vehicles to turn around.
Updating of the physical load posting signs is required for the AASHTO legal loads, as well as for the Specialized Hauling Vehicles (SHV) and Emergency Vehicles (EV) and the City of Everett is currently implementing these changes.
The cast-in-place non-redundant concrete girders are deficient in shear capacity as well as deck design. Although the bridge is designed for H20-S16 design truck, its deck is only designed for an H-15 design truck loading. Due to these deficiencies, it is not surprising that the deck is showing signs of distress under modern loads, even in its load-posted status.
2.3 Seismic Vulnerability Analysis – The bridge was also evaluated for seismic vulnerability and was determined to be a collapse risk during a seismic event. A nonlinear pushover analysis shows that plastic hinges will be formed at the base of the columns of bents 2 and 5 under a design seismic event. Moreover, the girder seat lengths at east and west abutments are not sufficient.
3. CONCLUDING REMARKS
The results of the structural assessment of the Edgewater Bridge has revealed that the bridge has not only vertical load capacity deficiencies but is also at risk seismically.
The in-depth inspection and the new load rating analysis show the bridge to be deficient for all the analyzed rating trucks. The loss of capacity supports the updated Deck Overall condition code reported in the bridge inspection software and the resulting Sufficiency Rating of 11.71 SD.
The lowest load rating value is associated with the bridge deck and is mainly caused by its substandard design and existing deterioration.
4
Furthermore, since the bridge deck is an integral part of the girders, its continued deterioration will result in an anticipated lowering of the Superstructure Condition code per the Washington State Bridge Inspection Manual.
As part of the analysis, a preliminary seismic study of the bridge was performed. Per this study, the Edgewater Bridge was found to be a vulnerable during seismic events and at risk of total collapse.
Finally, the bridge is deficient functionally with its narrow traffic lanes and sidewalks.
These results and observations support the replacement of the Edgewater Bridge. Please see Appendix C for a preliminary replacement bridge concept, Appendix D for an associated construction cost estimate, and Appendix E for an updated funding application form.

Notes
0 Bridge is oriented from west to east. Abutment 1 is at West (Mukilteo) end.
11 Bridge design load is H20-S16 but the design load for the roadway slab is H-15. The worst case and controlling design load code has been entered. The substandard deck design along with widspread positive moment zone deterioration such as full depth leaking rusty leaching cracks indicating deterioration of reinforcing steel and rusty reinforcing steel exposed by spalling concrete have resulted in an additional reduction of capacity of the bridge.EV2 R.F. = 0.43EV3 R.F. = 0.45The bridge is currently load posted. The posting requires updating for legal loads as well as for the Single Unit Vehicles and Emergency Vehicles.
12 Not visible due to ACP overlay.
35 SOFFIT: Widespread leaching hairline map cracking, some rust stained, with cracks primarily oriented longitudinal and transverse, are predominant along the centerline of the soffit. Many full depth cracks leaking water through during rainy day inspection. Stalactites present up to 4" in length. In Span 3 between floorbeams 3B and 3C there is a 12 in. dia. x 1 in deep spall with 6 in. exposed rusty rebar. There are many other scattered 6" to 1" delams and spalls with exposed rusty rebar up to 48" total at dobie chair locations in spans 2 through 5, with most in spans 3 & 4 near pier 4. A rough count of 14 spalls made in 2014 with other patches visible that appeared to be on the verge of spalling. The majority of the widespread soffit deficiencies such as full depth cracks with water leaking and rusty leaching, along with the spalls and delaniminations are located in the positive moment area of the deck. The deficiencies, their location, coupled with the substandard deck design prompted a new load rating that confirmed the loss of structural capacity. See notes 11 and 1663.
110 Two lines of CIP concrete girders x 5 spans. Concrete girders have vertical and diagonal hairline leaching cracks in the webs at 3' to 7' spacing throughout, some full depth. Multiple shear and flexure cracks in both girders = Monitor. Monitoring: -11/2010: Vertical shear cracks noted @ 1A, 1B, 3 each. Several cracks are obscured by graffiti. Shear cracks @ P1A marked. Cracks on 1B marked "08" do not appear to have changed. Vert cracks noted @ 2A, 2B marked '08 are nearly full depth, with no change evident. Horizontal leaching crack noted @ 1B. -11/2012 no change. -2014: Girder 1B crack measured at 1/32" which is among the widest observed. Many cracks appear to be full depth now. Leaching more in spans 1 & 2.
155 Floorbeams have transverse hairline cracks at the interface of the deck, mainly at the centerline. There are a few vertical hairline leaching cracks near the top of the floorbeams. Some of these are full depth 2014 on intermediate floor beams. Main floor beam at pier 4 with minor leakage/small rust stain on bottom. Floorbeam 1A with bottom edge spall, 2'x2" @ midspan - no exposed rebar.
205 Six feet wide at bottom tapering to 5' at top, with a rectangular construction stepped in at the edges. Column 4B is covered with vines over the whole length - 2014, making identification of defects difficult. Columns with random minor leaching up around corbel areas and around upper construction joints.
215 Consists of concrete cross beam supported by steel rocker bearings. Located just behind remains of previous abutment. There is an erosion gully at the SW & NE abutments from water leaking through the sliding plate joint above -- CB near adjacent SE intersection is overgrown and sounds disconnected - clear vegetation and investigate. See photos #2 and #3. Shrinkage cracks noted @ X-bm CL. Small corner spall located @ A1. Water appears to be leaking thru both expansion joint and SW fill slope and ponding @ thepile cap causing corrosion @ the bearings / sole plates. Also, erosion @ NW slope from water leaking through joint leaving 3' deepgully below.
221 The Northwest corner of the footing at Column 3B is exposed up to 32 in. due to erosion caused by a leaking storm drain See photo #9.
266 Sidewalk overhang is supported by concrete corbels each side of the bridge. Overhang has partial construction joints located between corbels. Sidewalk is worn to aggregate and has transverse and longitudinal hairline cracks. There are transverse hairline leaching cracks in the sidewalk soffits and diagonal hairline cracks in the haunches with leakage throughout. The NE & NW sidewalk approaches have been feathered with ACP eliminating tripping hazard but not to ADA standards. Curb joints on south sidewalk at midspan with spalling at deck drain. SE sidewalk approach with up to 1" settlement = repair.
311 Bottom plate with moderate section loss at west abutment up to 1/4" and welded steel girder stops with heavier section loss. More severe section loss at east abutment, especially at SE with section loss along bottom of rocker on exposed edges. There is a 16 in. x 4 in. spall in grout pad along the south end of the sole plate at the east abutment with no exposed rebar noted. SE bearing is corroded thru @ outside end - outside stiffener plate is gone -- REPAIR to maintain capacity. Rocker bearings at A6 are 1" out of plane rocked east.

664 Deck drains are open 2016 (8 locations). NW drain pipe @ A1 with cracked connection causing slope rilling at abutment footing = repair.
800 ACP overlay is worn in the wheel lines with minor rutting, and transverse and longitudinal cracks throughout. 2014 - Heavier wear/pavement failure over 25sf and 20 sf patches.
901 Paint system allows for 5 sq. ft. at each bearing only. Paint at bearings is flaking and exposing bare metal.
1660 The bridge's capacity is 44% below legal for the AASHTO-1 Truck.
1663 See load rating note 11. The substandard design load coupled with the widespread positive moment zone leaking rusty leaching cracks, spalling, and section loss have been assessed in the updated load rating. The loss of capacity along with the criticality of the deterioration based on their locations and the deficient deck design have resulted in a deck overall condition code reduction to 4 - Poor Condition.
1680 Small stream flows south to north under span 3. Piers 2 & 3 well above and back from OHW. Base line sounding taken from south bridge rail (2016).
1686 New transitions/guardrails/terminals at all 4 corners (2014).
2675 A 10 in. diameter dutile iron pipe is mounted to the concrete baluster on the south side and a 6 in. diameter gas pipe is mounted to concrete baluster on the north side. 18" storm line @ SE slope w/ outfall under span 3 into gabion baskets working as designed.
2688 The bridge received an in-depth inspection on June 30, 2017. This inspection focused on the deck soffit and the superstructure. The results of this inspection were used to perform a new load rating in July 2017. The inventory coding was updated per this current in-depth capacity analysis.
