The Regional Municipality of York is investing in building a safe, efficient and reliable Regional transportation network for all users.

Improvements to Leslie Street and St. John’s Sideroad in the Town of Aurora, Town of Newmarket and Town of Whitchurch-Stouffville are underway to accommodate growth and improve traffic flow.

Improvements include:

• Widening Leslie Street to four lanes from Wellington Street to Mulock Drive to improve traffic flow
• Widening St. John’s Sideroad to four lanes from Bayview Avenue to Leslie Street to meet the needs of travellers in the area
• Enhancing street lighting, installing on-street bike lanes, constructing sidewalks, building a multi-use path and improving landscaping to support cycling and walking along Regional roads and provide more travel options for residents
• Replacing existing culverts with larger culverts or bridges to allow for the safe passage of fish and wildlife and to improve creek flow
• Replacing and updating traffic signals to improve intersection accessibility to meet the needs of our communities today and into the future
• Reconnecting 14 kilometres of water course by removing barriers and enhancing existing streams to allow for more fish habitat
