I-40/I-240 INTERCHANGE

Phase I of project. Added flyover WB I-40 (east) toWB I-240. Added portion of ramp from WB I-40 to WB I-40 (north)

Phase II-A - Complete ramp structure from WB I-40(east) to WB I-40 (north). Add ramp from EB I-40 (north)to EB I-40 (east).

Phase II-A - Complete ramp structure from WB I-40(east) to WB I-40 (north). Add ramp from EB I-40 (north)to EB I-40 (east).

Phase II-B (Now Phase III)

– Reconstruct interchange to add through lanes fromI-40 (north) to I-240.

Phase II-B (Now Phase III)

– Repurpose existing roadways to serve as Collector-Distributor (CD) roads for ramps

Level of Service Traffic Analysis

– AM and PM peaks

– I-40 east & north

– I-240

– Covington Pike

– Sam Cooper

– All associated ramps

Findings for New “Phase II” and “Phase III”Freeway Sections

– I-240 WB & EB unsatisfactory (LOS E or F) by 2016

– I-40 WB (east) unsatisfactory by 2015

– Weaving sections okay but marginal

– Ramp Junctions have merge/diverge problems in nearfuture

Current Design Phase II

I-240 Addition of one (1) auxiliary lane on both east andwest sides

Widen existing bridge over Greenway

Relocate Ramp from EB I-240 to EB I-40 and widento three (3) lanes

Widen Ramps from EB I-40 (east) prior to split tofour (4) lanes.

I-40 (North) - Widen existing WB I-40 bridge overSummer Avenue

Ramp to be improved and remain open for local accessfrom WB I-40 (east) to Summer Avenue

Ramp from Summer Ave to be relocated east to allow forconstruction of other ramps

Ramp from WB I-40 (north) to be relocated east to allowfor construction of auxiliary lanes

Construct Ramp from EB I-40 (north) to EB I-40 (east) andrelocate entrance

Complete Ramp from WB I-40 (east) to WB I-40 (north)

Frontage Road relocated east and access toSummer Avenue relocated east

Sam Cooper Boulevard – Addition of one (1) lane in boththe EB and WB directions. Requires a design exceptionbe requested due to substandard shoulder widths.

I-40 (East) - Addition of auxiliary lane EB I-40 fromRelocated Ramp to existing lane addition near SycamoreView Road

I-40 (East) -Addition of two (2) auxiliary lane WB

I-40 (East) -Replace Wolf River Bridge.

I-40 (North) - Add two (2) auxiliary lanes from up toCovington Pike Interchange.

I-40 (North) - Replace Covington Pike Bridge toaccommodate auxiliary lanes

I-40 (North) - Continue an additional auxiliary lane WBfrom Covington Pike

Covington Pike Interchange - Widen Covington Pike toallow for dual left turn onto EB I-40 entrance Ramp

Covington Pike Interchange - Widen EB I-40entrance Ramp to allow for a dual-left turn lane.

I-40/I-240 INTERCHANGE

Covington Pike Interchange - Widen and shift exitramp EB I-40 to Covington Pike to provideadditional queue storage space off I-40.

I-40/I-240 INTERCHANGE

Covington Pike Interchange - Widen Ramp fromWB I-40 (north) to Covington Pike. Add exclusiveright-turn lane and additional queue storage
