JEFFERSON — The southbound lanes of South Clearview Parkway between Mounes Street and Jefferson Highway will be closed from 8 p.m. Friday to 8 p.m. Sunday as crews working on the Huey P. Long Bridge widening project repair the roadway.

When complete, the Huey P. Long Bridge will include three 11-foot lanes in each direction and feature 8-foot outside shoulders and 2-foot inside shoulders. The existing 18-foot-wide driving surface will be more than doubled to 43 feet.

The cost for the bridge widening is $1.2 billion.

The project is set to be complete June 16.
