The future of public transit in the Interstate 94 corridor between Minnesota and Wisconsin shed a couple of “ifs” this week when transportation officials and consultants declared a dedicated St. Croix River crossing a no-go.The Gateway Corridor Commission has decided if a light rail transit (LRT) line or bus rapid transit (BRT) line is built from the Twin Cities to the border, neither one will cross the I-94 St. Croix bridge.The Gateway Corridor Commission, an organization studying options for public transit in the corridor, cited space constraints on the bridge as reason for modifying portions of four of eight transit alternatives for the corridor under review. Any BRT or LRT option built along this section of I-94 would be planned to end at Manning Avenue in Woodbury, which is about four miles west of the bridge.
