The following is a news release from the Louisiana Department of Transportation and Development:
BATON ROUGE, La. – The Louisiana Department of Transportation and Development (DOTD) announced today that bids will be taken on Dec. 15 for a project that is designed to improve safety on roadways in the Lake Charles area.
Work on the estimated $1 million to $2.5 million project will involve installing centerline rumble strips on over 229 miles of state highways in DOTD District 07, which includes Allen, Beauregard, Calcasieu, Cameron and Jefferson Davis parishes.
Centerline rumble strips are grooved patterns that are grinded into the center of a roadway. They work by producing a noise and vibration that alerts drivers that they are beginning to leave their travel lane. Installing centerline rumble strips is a way to prevent head-on collisions and opposite-direction sideswipe crashes on two-lane roadways. According to the 2010 Highway Safety Manual published by the American Association of State and Transportation Officials, installing centerline rumble strips can reduce these crashes by 15%.
"The safety of the traveling public is the number one priority at DOTD," said DOTD Secretary Sherri. H. LeBas. "Installing centerline rumble strips is yet another way that we can help to prevent crashes and increase safety on Louisiana's roadways."
Work on the project should begin by spring 2011 and finish in summer 2011. The project is being funded using Federal Highway Safety Improvement Program Funding at a cost share of 80% federal funds and 20% state matching funds.
This project is part of a statewide safety initiative to install centerline rumble strips on over 2,100 miles of state highways. DOTD will accept bids for all of the projects by the end of the year.
The Louisiana Department of Transportation and Development (DOTD) is committed to delivering transportation and public works systems that enhance the quality of life. In addition to more than 16,600 miles of roadway, including over 890 miles of interstate, DOTD supports the development of the state's aviation, marine and rail infrastructures. Through this work, we are able to facilitate economic development, create job opportunities, improve vital evacuation routes, and make critical freight corridors safer and more efficient.
