Location: Mobile, AL
Client: Alabama Department of Transportation (ALDOT)

The Alabama Department of Transportation selected Volkert to prepare feasibility and environmental studies and other preliminary assessments and plans for the construction of a new, six-lane bridge and the widening of the existing I-10 Bayway across Mobile Bay to alleviate severe congestion and overuse of the current I-10 Mobile River crossing, the Wallace Tunnel.

Volkert’s services include engineering and environmental studies as well roadway alignments, bridge design concepts, functional design, and construction cost estimates. Volkert has also conducted traffic studies, including an origin-destination study, traffic counts, traffic projections, benefit/cost ratio, capacity analysis, and traffic modeling. Volkert provided substantial agency coordination and public involvement and prepared the EA, which was approved by the FHWA.

Volkert is currently updating environmental and engineering studies for an EIS.  Four Build Alternatives, are being studied in the EIS.  Environmental services include:

  • wetland evaluations
  • floodplain mapping
  • historic structures surveys
  • archaeological surveys
  • viewshed impact assessments
  • hazardous materials assessments
  • threatened/endangered species surveys

  • air analysis
  • Environmental Justice assessment
  • socio-economic studies
