A long-awaited state feasibility study of the busy La. 30 corridor in Ascension Parish will be revealed in a meeting Tuesday from 4 p.m. to 6 p.m., state highway officials said.

The state Department of Transportation and Development is considering a series of possible improvements to La. 30 in Gonzales, including roundabouts at the La. 30/Interstate 10 interchange.

State highway and city officials have been eyeing roundabouts for the interchange to help improve traffic flow at least since late 2013 but concerns from surrounding businesses prompted the agency to do a broader corridor study in March of 2014.

The feasibility study, which focused on a longer stretch of La. 30 between Ashland Road east to La. 44, was originally supposed to be finished in March 2015 but has run into delays, city officials have said previously.

DOTD spokesman Bill Grass said Monday that improvements being considered to La. 30 include a left turn lane at Veterans Boulevard and another eastbound lane from Ashland to Cabela’s Parkway.

That’s where the existing four-lane section of La. 30 begins and extends to the I-10 eastbound on-ramp. Both projects were identified early in the feasibility study, Grass said.

The study has also looked at roundabouts along the length of the La. 30 corridor and at I-10, or J-turns along the corridor with interchange improvements.

DOTD officials and their consultants will be present Tuesday to hear from the public and answer questions at the Gonzales Civic Center, 219 S. Irma Blvd.

Written statements can be mailed to CB&I Attention: Kara Moree, 4171 Essen Lane, Baton Rouge, LA 70809, but must be postmarked within 10 days of the meeting.
