The PMH1 Project includes highway widening from the east side of the new Port Mann Bridge in Surrey to 216 Street in Langley. The PMH1 Project includes plans for a new interchange at 216 Street. Transit improvements include a Park&Ride facility at 202 Street, which will connect Langley to the new RapidBus service over the Port Mann Bridge. A new underpass will connect the community of Walnut Grove, to the north of Highway 1, and the Park&Ride, to the south of Highway 1. This will add a new north-south connection for Langley and will improve traffic flow, and will create a link to the Golden Ears Bridge.  Environmental enhancement projects are also planned, including improvements to drainage and habitat areas.​
