Stroudwater Pedestrian Bridge

Acorn provided civil engineering and permitting services to Portland’s Parks and Recreation Department for a pedestrian bridge crossing over the Stroudwater River between the I-95 and Congress Street crossings.  The project included relocation of a pre-fabricated 74’-2” span steel bridge to span the bank to bank width of the Stroudwater River.  Acorn provided hydraulic modeling services to generate the 100-year flood elevation at the proposed crossing to determine bottom chord elevation, as well as trail and bridge ramp alignment design to match into the existing Portland Trails Network in the vicinity.  The design and modeling was performed to show the proposed project meets local floodplain code to better streamline the floodplain management permitting process at a local review level.  Acorn also coordinated survey, geotechnical, and structural subconsultants to produce construction drawings, and provided construction administration services through completion of the project.  The bridge will serve as a key connection into the Portland Trails walking path network and provide more multi-modal transportation opportunities to the greater Portland area.
