Vancouver, British Columbia – Drivers in Metro Vancouver are being warned to note new traffic pattern changes due to the Port Mann/Highway 1 Improvement Project. The changes include construction speed limits from Vancouver to Langley, and significant traffic pattern changes at the Vancouver/Burnaby border and in Surrey as drivers approach the Port Mann Bridge.
In Burnaby, drivers exiting Highway 1 westbound at Willingdon Avenue to destinations north of the highway will find that rather than exiting the overpass and merging with traffic on Willingdon, they will proceed under the overpass and take the off-ramp loop to Willingdon. There, a signal-controlled intersection will allow for turns onto north or south Willingdon.
A similar configuration will be put in place south of Highway 1 at Willingdon in early 2011. The changes are designed to allow for construction of the new, wider Willingdon overpass, reducing traffic weaving and improving safety.
In Surrey, at the 152 Street interchange, construction includes north and south retaining walls and abutments for a new overpass, as well as construction of a new on-ramp to Highway 1. The 110 Avenue on-ramp to Highway 1 from Fraser Heights is now permanently closed. Drivers who previously accessed Highway 1 from 110 Avenue will now do so from 160 Street, or from 152 Street via 156 Street and 104 or 108 Avenue.
Drivers are also reminded that over the summer, new construction speed limits came into effect on Highway 1. Between the Cassiar Tunnel in Vancouver and Grandview Highway in Burnaby, the maximum speed is 70 km/h, while between Grandview Highway in Burnaby and 208 Street in Langley, the limit is now 80 km/h.
