TKDA was a major participant in the design-build project to reconstruct the TH 36 and TH 95 interchange in anticipation of a new bridge crossing over the St. Croix River. TKDA provided highway and drainage design of TH 95 and structural engineering services. TKDA provided the design for Bridge 82043, a three-span prestressed concrete beam structure with a total length of 320 feet. The cast-in-place concrete bridge carries two lanes of Beach Road and a pedestrian trail over two eastbound lanes and two westbound lanes of TH 36. Also included are a two-lane on-ramp from TH 95 to westbound TH 36 and a single lane off-ramp from eastbound TH 36 to TH 95.
