This project has been thrown around for years now, but we're finally close enough to construction I think it's time for this to get a thread.
Background: essentially, the West Davis Corridor is a future freeway in northwestern Davis County. It has been planned in some capacity since at least 1996, when it was included as part of the governor's Legacy Highway proposal (this also included what became the Legacy Parkway and Mountain View Corridor). A few planning studies were done in the 15 years following, but a draft EIS wasn't done until 2013. UDOT learned from the lawsuits that had plagued Legacy Parkway and engaged environmental groups early on, who naturally opposed the planned freeway and proposed a "shared solution" that would only widen existing roads and add transit. The good news is that a compromise was worked out. Similar to Legacy just to the south, the freeway will have dark sky lighting, noise reducing pavement, and ground-level construction, and there will be a new multi-use trail paralleling the new road. But unlike Legacy, from the beginning the speed limit will be 65 and trucks will be allowed.
The initial phase will build a 4-lane freeway northwest from I-15 and Legacy in Farmington to Antelope Drive in Syracuse, with additional interchanges at Shepard Lane, 200 North in Kaysville, 2700 West in Layton, and 2000 West in Syracuse. Beyond Antelope, it will continue as a super-2 to 1800 North in West Point. Construction is supposed to start this fall and last all the way through winter 2024.
