TH 610 Design-Build

SRF provided lead design services and construction quality management on the TH 610 Design-Build, which extended TH 610 from TH 169 west to Hennepin CSAH 81. In addition to designing 2.75 miles of new four-lane freeway, SRF was responsible for:

• Converting the partial interchange at TH 169 to a full cloverleaf interchange.
• Designing overpasses provided at Jefferson Highway, Revere Lane, Zachary Lane and Hemlock Lane and a pedestrian overpass at Nathan Lane.
• Designing interchange access ramps at the Zachary Lane overpass and CSAH 81.
• Designing noise walls along the residential areas
• Lining an MCES interceptor sewer and reconstructing the manholes
• Roundabouts at Zachary Lane interchange ramp terminals
• Grade raise of TH 610 profile to eliminate the need for concrete retaining walls, and allow for a ditch along the north side to convey offsite storm water runoff from over 230 acres
• Spread footings and semi-integral abutments for the new bridges

Extensive utility coordination was performed to facilitate relocation of many existing utilities. An existing 345 Kv GRE transmission line along the north edge of the corridor required careful design and analysis to provide a maintenance road to each tower and avoid impact to the facility.

Responsible for overall design and construction quality, SRF led a quality management/quality control team that worked closely with MnDOT verification staff and ensured critical activity points were completed on time.
