Commuters traveling along the I-20 corridor may notice structural repairs during the next year.
It’s part of a $3.8 million project to rehabilitate 14 bridges/overpasses on I-20 in Bossier City. The majority of the work is being conducted on the side and underneath the structures, so disruption to traffic is expected to be minimal.
Overpasses included in the project are:
-Two at KCS/Westerfield Rd.
-Two at US 71/KCS -Two at LA 72 (Old Minden Road)
-Two over RR tracks between Old Minden and Airline Drive
-Two at LA 3105 (Airline Drive)
-Two at LA 72 spur (Old Minden Road)
-Two at LA 782-2 (Industrial Drive)
These structures are included in a list of the most-traveled structurally deficient bridges in Louisiana, according to a report released earlier this year by the American Road and Transportation Builders Association. Louisiana ranks 11th in the nation for the number of structurally deficient bridges.
Using data from the Federal Highway Administration, the ARTBA releases an annual Deficient Bridge Report. Of the 12,910 bridges in Louisiana, 1,821 (or 14.1 percent) are classified as structurally deficient. This means one of the key elements is in poor or worse condition.
There are 50 structurally deficient bridges on the state’s Interstate Highway System. While some local bridges were classified as “deficient” in the report, Erin Buchanan, public information officer with DOTD, said they are still safe for travel.
The multi-million dollar project in Bossier includes repairs to the backwall at Westerfield Road.
“The backwall is the small retaining wall that supports the approach slabs and holds back the embankment under the approach slabs,” she explained.
Repairs to various rocker bearings, which prevent unwanted movement on the structure (especially structures that carry heavy volume traffic such as interstate overpasses) will be performed.
Additionally, the overpasses will be sandblasted and painted.
Buchanan said the project is expected to wrap up in Spring 2019, weather permitting.
