EAC Consulting Inc. provided the following services as part of this Project Development and Environment (PD&E) Study:

• Inspection of the bascule and approach spans as well as their load rating analyses
• The navigational study for the channel in order to determine the clearance and ship impact requirements for the bascule span

• The preparation and approval of a Section 4(f) document for the historic bridge and the adjacent historic sites. This required extensive coordination with SHPO and FHWA
