Bridge Repair Project at I-24 and Chestnut Street to Begin Soon in Chattanooga

Wednesday, August 09, 2017 | 10:12am

CHATTANOOGA, Tenn. – The Tennessee Department of Transportation will begin work this week on a project to repair the bridge on Interstate 24 East over Chestnut Street at mile marker 178.6 near the US 27 interchange.  The project will also make safety improvements on two other bridges in the same area, one over the CSX Railroad and one over US 27.  In addition to making major bridge deck repairs to the bridge over Chestnut Street, this project includes the installation of high-friction surface treatment on all of the bridge decks.  This area has an above-average crash rate, and this safety project should help to reduce that number. 

On Thursday and Friday nights, August 10-11, 2017, between 7:00 p.m. and 6:00 a.m. EDT, the contractor will begin shifting traffic and reworking overhead signs.  Once the traffic is shifted and the signs reworked, work on the project will begin.  If rain postpones this work, it will be rescheduled to take place as soon as possible.

During the project, the bridge on I-24 East will be completely closed to traffic and a detour using the Lookout Mountain/Broad Street ramp (Exit 178) will be used to move traffic around the work zone and allow it to continue on I-24 East.  Once I-24 East is closed for bridge repairs, all repair operations will be done using a continuous daily operation (7 days per week) until necessary repairs are completed and/or all lanes are open to the free, unrestricted flow of traffic.  Additionally, traffic accessing Lookout Mountain/Broad Street from US 27 South will be detoured until completion of the project.

Dement Construction Co., LLC of Memphis is the contractor for the $ 2,118,003.30 project, which is slated for completion by November 15, 2017.
