The bridge 27C10 is part of the 14.5-mile extension of the METRO Green Line (Central Corridor LRT), which will operate from downtown Minneapolis through St. Louis Park, Hopkins, Minnetonka and Eden Prairie, passing near Edina. It is a cast-in-place segmental box girder consisting of 5 spans (244’-360’-400’-360’-244’), 1,608 ft long and 32’-6” wide. The superstructure depth varies from 20’ deep to 8’ deep.

FINLEY provided full construction engineering services to the contractor for the construction of the bridge. These services included construction analysis and construction manual preparation, geometry control manual preparation, integrated shop drawings preparation, and both design assistance of the temporary works required to build the bridge and design office support during construction. FINLEY changed the location of the stability prop to reduce the unbalanced construction loads in the foundations of the pier columns. Also, the counterweight was relocated, from the bridge deck to the stability prop foundation to accelerate the construction and improve safety.
