PRAIRIEVILLE — A project to widen a 2.3-mile section of La. 73 in Ascension Parish that ties into Interstate 10 is set to begin late this month, state highway officials said.

The $15.5 million project will be one of the subjects discussed during a Louisiana Department of Transportation and Development open house meeting from 6 p.m. to 7:30 p.m. Oct. 27 at St. John the Evangelist Church, 15208 La. 73, Prairieville.

The Oct. 27 meeting is designed to provide information about the La. 73 project, a separate widening project on La. 42 still several years off and other road jobs, DOTD officials said in a news release.

The La. 73 road job will add a third, continuous center turn lane to the two-lane highway between Airline Highway and the I-10 and La. 621 area.

That section of La. 73 threads through some of Ascension’s fast-growing areas.

Driving lanes on La. 73 will be widened from 11.5 feet to 12 feet and shoulders will be 6 feet wide.

As part of the job, parish government must spend $3.2 million to lay down sewer lines under the new highway, parish officials said.

During construction, two traffic lanes will be open except for periodic lane closures that usually would not be timed to interfere with periods of heavy traffic, DOTD officials said.

The project is expected to be finished in the summer 2013, DOTD officials said.

In addition to parish funding, the project is being paid for with $8.3 million in state surplus funding from fiscal 2006-07 and 2007-08 and $4.3 million in federal Congestion Mitigation and Air Quality Improvement Program money, DOTD spokesman Dustin Annison said.

The construction cost came in about $3 million under estimate. Barber Bros. Contracting Co. LLC was the low bidder with an offer of $15.5 million.
