Work on the new interchange at Northeast 139th in Vancouver will cause an overnight closure of I-105 southbound, starting tonight and going until 5 am tomorrow morning. Five new concrete girders will be installed overnight. Detours will be posted; traffic heading to Legacy Salmon Creek will need to get off the freeway at the Northeast 179th Street exit, next to the Clark County Fairgrounds. Additional closures are planned for this fall, as other new girders are installed and the old 134th Street overpass is demolished.
