British Columbia Highway 91

Alex Fraser Bridge carries BC-91 over the Fraser River

The total distance covered by Highway 91 is 22 km (14 mi). Starting at its junction with Highway 99 in East Delta, the route travels north for 2 km (1¼ mi) to a junction with Highway 10, then north for 10 km (6 mi) through three interchanges, over the Alex Fraser Bridge onto Annacis Island, and through another interchange. Highway 91 then crosses the Annacis Channel bridge, ever so briefly passing through the very corner of New Westminster, and then enters Richmond, at which point it veers west. At the southern entrance to Highway 91, the road was formerly signed as Annacis Highway, however, that name is not commonly used.

In Richmond, where Highway 91 is officially termed the Richmond Freeway but also as the East-West Connector, the route travels west for 10 more km (6 mi), through a junction with Highway 91A and two more interchanges, until it terminates just past its Richmond junction with Highway 99 at Shell Road.[2]

From south to north. The entire route is in Metro Vancouver.

Highway 91 Connector (Highway 91C) is a short 2.2 km (1.4 mi) unsigned highway connecting Highway 91 at Nordel Way and Highway 17 in Delta.[17] It formerly started at the BNSF Railway level crossing on 96 Street. Today, the route starts at a trumpet interchange with Highway 17, crosses over Highway 91 via twin overpasses, and ends at the BNSF overpass on Nordel Way.

From its opening, the route faced heavy congestion due to the presence of a truck scale and at-grade intersections. The Highway 17 and Highway 91C intersection saw several truck rollover accidents since its opening in 2013 and engineer's report revealed that trucks are susceptible to rollover when exceeding 26 km/h (16 mph) while turning from Highway 17 to Highway 91C.[18] The report recommended installation of truck rollover warning sign and an advisory speed limit of 20 km/h (12 mph) with the ultimate long-term solution to be an upgrade to grade-separated interchange.[18]

In 2017, the Province announced Highway 91C will be upgraded to a freeway standard as a part of $254 million project.[19] However, the project was partially downscaled and two at-grade intersections remain in the Highway 91/91C interchange. Traffic from southbound Highway 91 and westbound Nordel Way flows freely, while signals remain for traffic movements on the new southern overpass.

The grade separation work on Highway 91C started in 2020 and free-flow interchanges were constructed at Highway 17 and Nordel Way (west) with improved partially at-grade connections for Highway 91 ramps.[20] The project reached substantial completion by the end of November 2022[21] with remaining works extended up until May 31, 2023.[22][23]
