LAPLACE – The Louisiana Department of Transportation and Development advises motorists of upcoming traffic signal adjustments at the intersection of LA 3188 (Belle Terre Blvd.) and St. Andrews Blvd. in St. John the Baptist Parish, scheduled to be active on the morning of Tuesday, October 3, 2023.

The adjustments will ensure that all motorists making left turns at the intersection will have fully protected signal phases at one point through the cycle. These adjustments will eliminate the current left turn “yield on green” phases.

DOTD appreciates your patience and reminds you to drive cautiously through the construction site and be on the lookout for work crews and their equipment.
