Road, Bridge, and Infrastructure Projects – Brock Road Corridor & Vicinity

Project lead: Ministry of Transportation of Ontario 

The Ministry of Transportation of Ontario is carrying out rehabilitation work in the Brock Road and Highway 401 area.  

This project will help maintain critical transportation infrastructure and support the safe movement of people and goods through an important regional corridor. 

Stage 4 is scheduled to run from April to September 2026 and will include work on the east side of Brock Road, the CN overpass structure, and the Highway 401 bridge. 

Construction highlights/impacts: 

• The eastbound Highway 401 on-ramp at Brock Road will close beginning April 6, 2026 for approximately 6 months. The nearest eastbound Highway 401 access points will be at Whites Road in Pickering and Westney Road in Ajax. 
• Crews will carry out short-term nightly lane and ramp closures as needed.  
• Traffic on Brock Road will be reduced to two lanes in each direction.  
• Timelines may change if the province approves a scope change to add a dedicated northbound Brock Road to eastbound Highway 401 right-turn lane.

Design is currently underway. Construction is anticipated to begin in July 2026 and conclude in early 2027. 

Construction highlights/impacts: 

• Adding second southbound left turn lane on Brock Road 
• Extended turning lanes on Bayly Street 
• Signal timing adjustments, and other capacity upgrades to support increased traffic to and from the Durham Live Site development

Project lead: Region of Durham  

The Durham-Scarborough Bus Rapid Transit project is a major regional transit initiative that will improve transit service across Durham Region and into Scarborough. 

As work advances, motorists will experience lane shifts, temporary lane closures, and other traffic changes near active construction areas, including sections affecting Pickering. 

Once complete, the project is expected to support more reliable transit service, improve travel times, provide enhanced cycling and pedestrian infrastructure, and strengthen connections across the region. 

Construction highlights/impacts: 

Preparation for the Kingston Road BRT segment from Steeple Hill to Merritton Road is underway, with construction expected to start in July 2026 and be completed by the end of 2028. 

The next segment, from Dixie Road to Bainbridge Drive, is expected to begin construction in August/September 2026 and be completed by fall 2029. This segment will directly affect the Brock Road and Kingston Road intersection and vicinity.

Project lead: Ontario Power Generation 

Ontario Power Generation is advancing preparations for the refurbishment of the Pickering Nuclear Generating Station, a major long-term infrastructure project that will support Ontario’s electricity system for decades to come. 

As planning and related work continue, residents may notice increased project activity and construction-related traffic in areas connected to the Pickering Nuclear site and surrounding road network. 

This project is expected to support long-term energy reliability, local employment, and broader economic benefits across Ontario. 

Construction highlights/impacts:  

• To help manage the impacts of increased daily vehicle and heavy-equipment traffic, the City is actively working with OPG on planned upgrades to Sandy Beach Road and Montgomery Park Road ahead of the refurbishment, as per the Council approved Road Servicing Agreement (Resolution # 767/25). 
• Phase 1 works on both roads were completed in 2025. Phase 2 works, which will bring the project to completion, are expected to commence in April 2026 and be completed by year end. Road closures and detour routes will be in effect during construction. 
• Pickering Nuclear Refurbishment work is scheduled to begin in January 2027 and span approximately seven to eight years.
