Following Hurricane Katrina, traffic volume and congestion increased rapidly at the I-10/I-110 interchange in D’Iberville, Mississippi. The Mississippi Department of Transportation (MDOT) recognized a critical need for improvements and selected Volkert to conduct engineering and environmental studies for upgrades to the interchange in order to improve the safety and mobility of the traveling public.
Volkert’s preliminary studies, services, and design achieve the improvements envisioned by MDOT:
- accommodate traffic flows predicted to reach 100,000 vehicles per day
- alleviate traffic congestion on nearby Popps Ferry Road, D’Iberville Boulevard, and Lamey Bridge Road
- improve access via local connector and distributor roads.
MDOT fast-tracked the project so design/build services could be initiated as soon as possible after right-of-way acquisition was completed.
Challenges included designing for construction under traffic, retaining vertical clearance, adding new lanes between existing piers, and accommodating a nearby park, mall, and apartment development. Volkert met project milestones, providing a Final Environmental Assessment within fifteen months, and satisfied all FHWA and NEPA requirements, including the approval of a Finding of No Significant Impact. Volkert’s services enabled MDOT to move quickly to final design and construction in an effort described by MDOT’s project manager as “teamwork at its finest.”
