BATON ROUGE, La. (AP) - Louisiana motorists may be surprised to know that the speed limit is 75 mph on a nearly 200-mile stretch of Interstate 49 generally between Opelousas and Shreveport.
The new speed limit, the highest in Louisiana, stems from a 2010 bill.
That measure authorized the state Department of Transportation and Development to raise the maximum legal speed when engineering and traffic investigations showed it could be done safely.
DOTD officials say their studies showed that 85 percent of drivers along the route were traveling at or below 75 mph.
The speed limit increased in St. Landry, Avoyelles, Evangeline, Rapides, Natchitoches and DeSoto parishes.
Jodi Conachen, communications director for DOTD, tells The Advocate there are no plans to raise the speed limit elsewhere.
