Comite river diversion bridge at LA 19 and La 19 railroad bridge

Location: East Baton Rouge, Louisiana
Dates: October 2019 – Ongoing

HUVAL designed all aspects of this CMAR project including the LA 19 Railroad Bridge.

The Louisiana Highway 19 Bridges Project is in East Baton Rouge Parish, Louisiana at the point where the channel of the future Comite River Diversion Canal (CRDC) will intersect existing LA 19. The site is located just north of Baton Rouge and south of Baker. The project includes both highway and railroad bridges across the Comite River Diversion Channel.

The new channel will pass under the existing at-grade Geaux Geaux Railroad running north-south through the area.  The new single-track railroad bridge will be approximately 350’ long over the completed channel.  Coordination with the railroad is critical in order to maintain rail service during construction.  A shoo-fly track will be designed for the maintenance of rail traffic while the new channel and new railroad bridge are constructed.

The highway bridges project scope of work includes preparing plans, specifications and design documentation for a portion of the CRDC, twin parallel bridges approximately 350 feet long, with a finished cross-sectional clear width of 40 feet on LA Hwy 19, and a single bridge approximately 350 feet long, with a finished cross-sectional clear width of 40 feet on Hwy 67. LA Hwy 19 and Hwy 67 traffic are being maintained via a parallel temporary diversion roadway.
