In this November 2016 photo, you are looking north at the future northbound SR 99 off-ramp bridge to South Dearborn Street. The new ramp is under construction just west of Seattle’s stadiums. Earlier in the week, crews working for Interwest Construction placed the 14 girders that will support the roadway deck.
