LAPLACE — The Louisiana Department of Transportation and Development announces a project to overlay ramps on Interstate 10 in St. John Parish to mitigate ramp flooding at the Belle Terre Boulevard/Louisiana 3188 interchange at I-10 during high water events.

Daytime ramp closures will be required for construction of the ramp overlays over a two-week period.

Work on the I-10 eastbound on-ramp is expected to begin Monday and continue through Aug. 1.

Work is expected to begin on the I-10 westbound off-ramp Aug. 4 and continue through Aug. 8.

Ramp closures will take place from 9 a.m. to 3 p.m.

Motorists may detour via U.S. 51 and U.S. 61 during both closures. DOTD will use in-house forces from the Hammond District to complete the work.

The project is an interim treatment until a future project can be implemented to elevate all ramps within the interchange.

“Although the I-10 westbound on-ramp will likely remain closed for some time during high water events, all other ramps should be passable once the water level falls to approximately the same elevation as Belle Terre/Louisiana 3188,” a release from the state transportation said. “U.S. 61 would serve as a detour until the westbound on-ramp could be reopened.”

The planned construction activities are weather-dependent and may be rescheduled in the event of inclement weather, authorities said.

Emergency vehicle access will be allowed during the ramp closures.
