The City of Greater Sudbury is widening Municipal Road 35 (MR35) from Notre Dame Street East, Azilda to Highway 144, Chelmsford. The new roadway will include road widening to four lanes from Notre Dame East to Notre Dame West and to five lanes from Notre Dame West to Highway 144 (including a continued shared centre turn lane). In addition, the new roadway will include intersection improvements, traffic signal upgrades, paved shoulders with rumble strips, drainage improvements, new signage, pavement markings and guide rails, where required. Approximately 975 metres of water main upgrades will also be undertaken near the Chelmsford section of this corridor.
