Lexington Parkway Pedestrian/Bicycle Trail

TKDA increased bicycle and pedestrian safety and accessibility with new trail and tunnel

TKDA provided design for a 0.3 mile long pedestrian/bicycle trail along Lexington Parkway in the Midway Area of Saint Paul. To provide a safe crossing at the intersection of the bicycle trail and the BNSF mainline track, TKDA designed a 12-foot-wide by 14-foot-tall tunnel extending below the BNSF tracks. The tunnel included approximately 154 feet of cast-in-place concrete retaining walls at either end.

TKDA also provided construction administration services which included construction staking, MnDOT-certified construction inspection and contract administration. Using precast concrete box culvert sections the construction of the tunnel below the BNSF Railway double mainline was completed during a 30-hour work window. Through TKDA’s services all phases of the project were completed in accordance with the requirements of federally funded projects.
