Turning northwest along Interstate 110 northbound between Scotlandville and Baton Rouge Metro Airport (BTR). 05/19/14
Interstate 110 winds north through Baton Rouge, joining I-10 with Downtown, the State Capitol and Baton Rouge Metropolitan Airport (BTR). The urban spur provides a high speed route to U.S. 61 (Scenic Highway) leading north from Scotlandville in north Baton Rouge to southern Mississippi. The freeway carries six lanes north to LA 19 (Scotland Avenue) and four lanes on the western leg to Scenic Highway. Speed limits are posted at 50 miles per hour on the substandard portion to the south and 60 miles per hour on the more linear stretches to the north.
A four level interchange joins Interstate 110 with U.S. 61/190 (Airline Highway) east of the Mississippi River Bridge. U.S. 190 and I-110 form part of an incident detour for I-10 and the Horace Wilkinson Bridge.
Initial construction for Interstate 110 took place by 1956 east of Capitol Lake and south of Memorial State. Named the Baton Rouge Expressway (LA 3022), the short segment opened south to North Boulevard and north to LA 67 (22nd Street) by 1961. The viaduct system south to Interstate 10 was completed by 1963, allowing a fast route from Downtown to the eastern suburbs and I-12.
Early plans for Baton Rouge outlined a full loop north from Interstate 10 using a portion of U.S. 190 (Airline Highway) and the Mississippi River Bridge. This included a new terrain alignment from I-10 north to U.S. 190 at LA 1145, and an upgrade of U.S. 190 east to a trumpet interchange with I-410 leading south to the Baton Rouge Expressway.
The urban Interstate numerology submitted to the American Association of State Highway Officials (AASHO) by the Louisiana Department of Highways on March 27, 1958 assigned Route B10 to the loop at Baton Rouge. Changed to Interstate 410 per correspondence with AASHO on July 2, 1958, the route was approved on November 10, 1958.
