Surrey’s Highway 99 interchange project moves forward, aiming to reduce congestion, improve access, and support rapid growth in South Surrey.
A major transportation upgrade in South Surrey is one step closer to becoming a reality.
As the community continues to grow at a rapid pace, city leaders are moving ahead with a long-awaited Highway 99 interchange project designed to improve traffic flow, support new housing, and create safer routes for drivers, cyclists, and pedestrians.
New Highway 99 Access Planned for South Surrey
The City of Surrey, working alongside the Province of British Columbia, is advancing plans for the 24 Avenue and Highway 99 Interchange Ramps project.
The proposed upgrade will add new north-facing entrance and exit ramps along Highway 99. As a result, traffic congestion in the area could ease significantly while providing better access for residents and businesses.
City officials say the existing transportation network is struggling to keep pace with population growth and future housing targets. Therefore, the interchange project has become a key part of Surrey’s long-term infrastructure strategy.
Major Road and Overpass Improvements Included
The project extends beyond new highway ramps.
Plans also call for improvements to the Highway 99 overpass and the widening of 20 Avenue between 160 Street and Oak Meadows Drive. The upgraded corridor will feature four traffic lanes, enhanced pedestrian facilities, dedicated cycling infrastructure, new traffic signals, and modern street lighting.
These changes aim to create a safer and more efficient transportation network for all road users.
Council Approves Preliminary Design Work
Surrey City Council recently approved a contract for the project’s preliminary design phase. At the same time, council authorized an agreement with the provincial government to share the costs of engineering design services.
According to city documents, the design work will include a new southbound off-ramp connected to a fully signalized intersection at 24 Avenue. In addition, a partial westbound-to-northbound right-turn on-ramp will be added.
The project will also upgrade active transportation routes. Existing sidewalks and cycling lanes will give way to wider multi-use pathways that extend beyond the highway ramps on both sides of the overpass.
Funding Decision Will Shape Next Steps
City staff expect the preliminary design phase to wrap up by November 2026.
However, the future of the project will depend on provincial funding approval. Until that decision is made, construction timelines and later project stages remain uncertain.
Croydon Drive Realignment Required
The interchange development will also bring changes to nearby road connections.
Croydon Drive, which currently runs parallel to Highway 99 and connects with 20 Avenue near the proposed overpass, will need to be closed at its existing access point.
To maintain connectivity, the road will be realigned and linked back to 20 Avenue in the future. That work will move forward once the necessary land becomes available through ongoing development projects in the area.
Another Major Upgrade Planned Along 24 Avenue
Meanwhile, Surrey is also preparing for another significant infrastructure project nearby.
The city has issued a request for bids for road and watermain upgrades along 24 Avenue between 172 Street and 166 Street, including improvements on adjacent side streets.
The planned work covers excavation, asphalt paving, road markings, signage installation, pedestrian and traffic signals, streetlights, drainage upgrades, and new underground water infrastructure.
Crews are expected to install roughly 1,200 metres of new watermain along 24 Avenue and another 820 metres along 172 Street.
Supporting Surrey’s Rapid Growth
With South Surrey continuing to attract new residents and development, transportation improvements are becoming increasingly important.
The Highway 99 interchange project and related infrastructure upgrades are expected to strengthen mobility, improve safety, and help the city accommodate future growth while keeping people and goods moving efficiently across the region.
