Location: Baton Rouge, LA
Client: Louisiana Department of Transportation and Development (LDOTD)

As part of the Louisiana Department of Transportation and Development’s “Geaux Wider” program, Volkert worked as a design-build partner to accomplish the widening of Interstate 12 from O’Neal Lane to Pete’s Highway in East Baton Rouge and Livingston Parishes.

The project entailed widening I-12 from 2-lanes in each direction to 3-lanes in each direction (6 lanes total), reconstruction of the existing lanes and replacement of the existing dual bridges across the Amite River. Volkert’s services included roadway design, electrical design, permitting compliance, and QA/QC assistance on the design plans for this project. Design Plan Sets included clearing & grubbing, erosion control, and maintenance-of-traffic for coordination of phased construction. Design plans for signing and striping, paving, storm drainage improvements and construction details were also developed for the project.

Volkert was also responsible for scour analysis for the substructure of the new Amite River Bridges, permitting, environmental compliance, public involvement, independent quality control, and engineering during construction. Scour analysis was accomplished by modifying the Amite River hydraulics model using HEC-RAS to include the substructure for the new bridge replacements.
