The proposed maps that I have from 2016 showed a "Scott Road Extension" that would have gone just west of 124th Street, between Highway 17 and King George, that would have had an on-ramp to the Pattullo Bridge along with a flyover that would have connected into Scott Road on the south side of King George. While there still would have been a light on Highway 17 where this would have connected for the westbound traffic (like there is at Bridgeview Drive) it likely would have been a bit of a shorter trip as there wouldn't be the extra light along Bridgeview to deal with; trucks could have just gone straight onto the bridge.
