Bay

Fulton, Aransas County

Constructed in 1967

Length: 9,232 ft

Two 13-ft Lanes; 2-ft Shoulders

Old Clearance: 50 ft

Undersized for Current Traffic Flow

Traffic Cannot Pass if Accident or

Breakdown

Structurally Deficient

ACM on Bridge

ACM: Bearing Pad, Railing Stanchion Gasket, & Sealant in Pier Core Hole

ACM = >1% asbestos; Regulated ACM = 260 LF pipe, 160 SF coatings, or 35

CF where length or area not previously measured

TDSHS Notification

TDSHS – 10-day Notification per NESHAP

and/or TAHPR

– Required for Demolition of a Bridge

Regardless of ACM Presence

– Combined or Separate Demolition and

Abatement Notifications

– Phased Demolition/Abatement:

• 3 Months Expanded to 12 Months

• 5 Abatement Notice Amendments

Traffic Control

Traffic Control Area Managed by Bridge

Construction/Demolition Contractor

Traffic Control may be Managed by ENV Contractor,

District Contractor, or Demolition Contractor

Project Conditions will Dictate the Most Cost-effective

Approach

District may Prefer ENV Contractor to Manage Traffic

Control for Abatement-only Projects

Requires Careful Coordination and Scheduling

Complex Traffic Control Plans to be Sealed by an Engineer

Require Use of Engineering Contract

ENV may Require Assistance Evaluating Adequacy of Plan

Careful Management of Liability Issues for TxDOT and ENV
