LA 1 and Sugar Plantation Parkway Intersection Improvements
The project will construct a J-turn at the intersection of LA 1 and Sugar Plantation Parkway. The J-turn
is a reconfiguration of the traditional intersection that is used in different parts of the country to improve traffic flow and safety.
DOTD has begun using this concept at specific locations across Louisiana. The J-turn concept is a method that safely and efficiently
manages high traffic volumes at intersections with multiple approaches along a divided highway.
The project is expected to be let out for bid March 2012 with construction beginning early Summer 2012. The estimate cost of the
project is $500,000 - $1M. The project is expected to take 7 months to complete. Once complete, traffic entering LA 1 from Sugar
Plantation Parkway or LA 1 Frontage Road (by Benedetto’s Market) will be allowed to turn right, enter the J-turn lanes and conduct a
U-Turn approximately 600 feet north and south of the intersection in order to head back to the left.
Additional “bulb-outs” or turning radiuses will be added at each U-turn location to allow ease of motion for larger vehicles such
as school buses and tractor-trailers. These will also allow additional acceleration for turning traffic to enter into the main lanes
of LA 1.
The entrance from Mouch’s Mobile Home Park to LA 1 will be closed to construct the bump-out on the south side of the intersection.
Traffic from the mobile home park will have to access LA 1 by turning right toward Benedetto’s or left to the next entrance further
south.
During construction, there may be times when lane closures are necessary. All closure will be communicated to the public via press
release, e-mail updates, Project page and Facebook page. Closures will not be allowed during peak travel times

US 167 and LA 699 Improvements
This J-turn was opened to the public on February 27, 2012. Work began on January 9, 2012.
This is part of a larger $3.5 million project along U.S. 167 from 0.6 miles north of the LA 14
Bypass to the Lafayette Parish line. This project resurfaced a 9.3 mile stretch of US 167 that
runs between Abbeville and Maurice.
"Roadway infrastructure is a key component in reducing traffic fatalities. The installation of this new J-Turn in Vermilion Parish will help to reduce the number of crashes occurring along this heavily traversed roadway."

This project will construct a J-Turn intersection, which have been used across the country to help traffic flow,
increase safety, and reduce travel time.
When the J-Turn intersection is complete, traffic approaching Ambassador Caffery on Chemin Metairie Road will no
longer have to wait for a signal to change, but will yield to traffic coming from the left before they pull out and
turn right. Once they pull out, traffic will cross to the newly-constructed far left lane where they can wait safely
until it is clear to conduct a U-turn to turn back on Ambassador Caffery. At this point they will be able to remain
on Ambassador Caffery or turn right to continue on Chemin Metairie
The movement of the J-Turns reduces the likelihood of crashes, especially severe crashes such as side-collisions.
Also, where the conventional intersection has 32 conflict points, where crashes can occur, a J-Turn intersection has
only 14 conflict points.
Also, because this intersection will not require a signal, drivers will see a decrease
in travel time because they will not have to wait on the signal when it is clear to proceed.
