PRAIRIEVILLE — One lane on the southbound Airline Highway span over Bayou Manchac will be closed for more than two weeks starting Tuesday to prepare for replacement of the bridge, state highway officials said.
The state is spending nearly $10 million to replace both Airline bridges over Manchac: the Ascension-East Baton Rouge Parish line and the southbound bridge over Bayou Francois in Gonzales to the southeast.
Contractors working for state State Department of Transportation and Development are also planning to do road paving work around the new bridges, DOTD plans show.
All three bridges being replaced on Airline, which is also known as U.S. 61, were built in the early 1950s and have reached their designed life expectancy, state highway officials have said.
The Manchac bridges are near the State Fairgrounds, which is BREC's Airline Highway Park, in Baton Rouge.
Construction is expected to start Monday on a nearly $10 million project to replace three aged bridges that cross bayous under Airline Highway…
Contractors will close the right southbound lane of Airline on Tuesday while they tie in a detour route to go around that bridge for the replacement work, highway officials said in a statement.
The lane closure is expected to last until Dec. 20.
Once finished, the southbound bridge at Airline will be closed and traffic on Airline will use the detour instead until a new southbound bridge is built.
The work on the new concrete span is expected to finished by the summer.
No vehicles wider than 12 feet will be allowed to pass through the lane closure area until Dec. 20, DOTD officials said.
Work began on the bridge replacement project in September. Last month, contractors instituted land closures and did other related work for a similar detour bridge at Bayou Francois in Gonzales.
