GONZALES — The La. 621 bridge over Black Bayou in Ascension Parish could be closed for repairs as much as five hours per day for a three day period next week, officials said, though the closures could end up being less than anticipated.

State highway officials said the closure on La. 621, an important, east-west route that cuts through eastern Ascension, will be two-tenths of a mile east of La. 44 north of Gonzales.

State Department of Transportation and Development officials said in a written statement that the closure is planned Monday to Wednesday between the hours of 9 a.m. to 2 p.m.

Rodney Mallett, DOTD spokesman, said in an interview on Friday that the bridge may not have to be closed on Tuesday.

Workers will be removing bad sections of pile under the bridge and replacing them, Mallett said.

The project, which is expected to cost $50,000, requires the road closures because of amount of space on the bridge that the equipment and the work itself will require, Mallett said.

Signs will be posted during the closures, directing east- and westbound traffic on a five-mile detour. Eastbound cars on La. 621 will head north on La. 44, east on 931 and south on La. 431 back to La. 621. Westbound traffic would take the reverse of the eastbound detour route.
