West Davis Corridor
« on: July 25, 2020, 01:39:46 AM »

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.

I’ve emailed a liaison from UDOT’s Region 1, who told me that this route will “NOT have an I designation” and in UDOT documents as part of SR-67; he even bet me a hamburger for it (whether I take it up that bet remains to be seen), as its still pretty early.

I don’t see how this can ultimately be numbered 67 without causing a lot of confusion, especially since a Glovers Lane terminus at 15/Legacy is confirmed now. It would have made more sense as a 67 extension if West Davis had ended at 15 around Shepard Lane, which was thrown around for a while before eventually being eliminated as a possibility.

Looking at the interchange configuration I don’t see how you can call West Davis a Legacy extension, especially because there is over 2 miles of existing Legacy between I-15/US 89/Park Lane and the future West Davis junction - so that would likely have to be renumbered as something else. If you did that, you’d be splitting one number between two distinct freeways and one freeway between two numbers.

My point exactly; I could see a split-ended SR-67, but that wouldn't make much sense either. I'm feeling that the West Davis Corridor gets a completely different number (not sure what, given UDOT's numbering of new numbers as of late).

Maybe I should take the UDOT rep up on his offer.

UDOT to build new $47M interchange in tandem with West Davis Corridor construction

Meanwhile, officials say another $47 million, major infrastructure project can be added to the list.

UDOT Program Manager Nathan Peterson said the state plans build a new Interstate 15 interchange at Shepard Lane in Farmington, which will also eventually connect to the WDC. Peterson said design work on the proposed interchange set to begin later this year and UDOT plans to coordinate construction to finish at the same time as the corridor.

Is there any chance this roadway might be extended further north in the future, say, all the way to Interstate 84?

It's interesting that they're building a normal interchange on I-15 at Shepard, because several iterations of WDC proposals actually had it terminating at I-15 there (and such an alignment was preferred by the city of Farmington). The proposed south end was only finalized at Glovers after it was determined that a potential 15/WDC interchange at Shepard would be too close to the existing 15/89/Legacy/Park Lane interchange to meet safety guidelines.

To be honest, as far as I'm concerned it's inexcusable that there is still a four-mile gap between interchanges on that part of I-15 to begin with. I get that this area was more rural back when the interstates were first being planned, but it's been fully urbanized for a while now. An interchange at Shepard Lane probably should have been built 20 years ago, back when the Park Lane interchange was reconfigured for Legacy and the US 89 freeway was built. (with an interchange at Shepard, even!)

Looking at the shape of the I-15 east-side frontage road, I wonder if an interchange was ever planned at the Burton Lane overpass further north. Would have been almost exactly halfway between the Kaysville and north Farmington interchanges.
