Posted to: Downtown, TransportationThomas Breen photo State St., looking north from Chapel: The northbound lanes (on the right) will be permanently going away; the southbound lanes (on the left) will be turned two-way. Big changes are coming to a downtown stretch of State Street Tuesday — as the current northbound vehicle travel lanes between Chapel and Audubon will be permanently closed, and the current southbound vehicle travel lanes will be converted to two-way. While these new changes will affect State Street between Chapel and Audubon, the Elicker administration has already closed the northbound travel lanes of State Street south of Chapel, down to Water. In the mayoral notice scheduled for 6 p.m. Monday, Elicker wrote that, after this change, there will be one travel lane in each direction as well as turning lanes on what is currently the southbound lanes of State Street. He said that all of this is part of the state-funded $6.7 million Lower State Street Redesign Project.
