A project to overlay 13 miles of Interstate 10 in Lafayette and St. Martin parishes is expected to begin by the end of 2013.

Louisiana Department of Transportation and Development officials say the estimated $76 million project is the largest on their 2012-2013 proposed priority list for the Acadiana region.

DOTD says the interstate overlay project is expected to begin by the end of 2013 and take about two years to complete.

Teddy Babin, with the DOTD's regional office in Lafayette, says the overlay will extend from the I-10 / I-49 interchange in Lafayette and continue to the Atchafalaya Basin bridge near Henderson.
