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.

The allocated funding had since been diverted for other uses, and as of 2011 the province had no intention of building the interchange,[4] but in April 2013, International Trade Minister Ed Fast announced that the removal of the traffic signal at 72nd Avenue would be given the go-ahead.

[5] On June 8, 2016, the BC government announced that the construction of a new interchange at 72nd Avenue, priced at $30 million, would commence in the fall, thereby removing the final traffic signals on Highway 91.

[12] A counterflow system with a movable barrier was added to help ease traffic during morning and afternoon rush hours.

The new seventh lane opened to traffic on September 14, 2019,[13] with the moveable reversible zipper in operation on December 16, 2019.

From its opening, the route faced heavy congestion due to the presence of a truck scale and at-grade intersections.

[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.
