On Nov. 21, the cones and detours on Broadway are scheduled to come down, and crews will put the downtown job away for the winter. That's a pause, though, and the job isn't done. The Wyoming Department of Transportation has a second round of work set for spring on the Broadway blocks between Jackson Street and Cache Street, and the whole project isn't expected to wrap up until June 15, 2027.
So downtown will spend the winter half rebuilt. Some corners near Town Square now have new ramps and sidewalks. Others are still waiting for their rebuild. Next spring the street goes back under construction for a few more weeks, and the corners you walk past daily will look different again by early summer.
Where the work stands this week
WYDOT has been running two projects at once around the Square since early October. One covers drain inlets, sidewalks and ramps on Broadway at Cache, Glenwood and Millward. The other is a full traffic signal replacement at Broadway and Millward.
The newest piece is on South Cache. On Monday, Nov. 2, South Cache Street closed from Broadway to the alley between Pearl Avenue and Broadway. Buckrail reported that the closure was expected to last 10 days while crews removed the old pavement and poured and cured new concrete.
Through Nov. 21, the rules WYDOT set for the work zone in its September announcement still apply:
- Lanes: Through traffic drops to one lane in each direction inside the work zone.
- Turns: No turns from Broadway onto North Millward Street.
- Trucks: Heavy vehicles and commercial traffic detour around the project on North Jackson Street.
- Sidewalks: Regular sidewalk access is restricted, and crews keep alternate walking paths through the construction area.
- Parking: Parking is restricted on Broadway and Cache inside the construction area.
All of it, including the detours and intersection closures, is scheduled to stay in place until Nov. 21.
Why the signal at Millward is being replaced
The signal work makes the most sense once you know why it's happening. On the Town of Jackson's 2026 construction page, the project's stated purpose is to replace the signal "to provide ADA ramps at the corners." The point is to rebuild the intersection for people on foot, and the new signal hardware comes along with that.
That's why the job has taken a full season. In its Oct. 19 update, WYDOT said a temporary signal was up while crews drilled shafts and ran conduit, with concrete work on the ADA corners underway and a target finish of Nov. 20. A few days later, Buckrail reported that crews were setting signal poles and planned to install four horizontal mast arms. The state's road information site lists the signal job as project N104096, with Modern Electric Co. as the contractor.
Cache moved faster. In mid-October, the Jackson Hole News&Guide reported that crews were pulling up concrete and working on drain inlets on the south side of Broadway and Cache, aiming to finish that intersection within the week before moving to Broadway and Glenwood. The South Cache closure this month is the next step, replacing the street surface past that corner.
What Nov. 21 stops, and what it doesn't
From the start, WYDOT described this as a two-season job. The September release said construction would run through late November, "with final phases resuming in the spring." WYDOT resident engineer Bob Hammond explained the timing in that same release:
"We tried to time this work to avoid the busy summer season and poor weather in winter."
That logic sets the whole calendar. Fall work ends before snow and plowing take over the streets. Spring work picks up after the snow and is scheduled to finish by June 15, 2027, before summer gets going. Each season of construction fits into one of the valley's two quieter stretches.
It also means this winter's downtown is an in-between version of itself. At some corners you'll walk across new concrete and ADA ramps from this fall's work. At others, the old corner is still there and waiting.
The spring list
When crews come back, according to WYDOT's Oct. 30 release, the work focuses on the core blocks of Broadway nearest the Square:
- Slab repairs on sections of Broadway's concrete from Jackson Street to Cache Street.
- Bulb-outs, curb extensions that push the sidewalk out into the street, to replace the remaining pedestrian corners.
- ADA ramps and sidewalks built with those new corners.
The Town's project description for the slab repairs adds new crosswalks, drainage inlets to the storm sewer, and curb and gutter repairs to that scope. WYDOT is also doing some of the curb, gutter, sidewalk and storm drain work on Broadway on the Town's behalf. Hammond said so in the release Buckrail quoted for its South Cache story.
The bulb-outs are the change you'll see most. Your car won't notice a slab repair, but a corner that juts farther into Broadway changes where you stand to wait at the light and how the edge of the street looks from the Square. By the June 15, 2027 completion date, the corners around Town Square should all match the new standard.
A season-by-season calendar
Here's how the project's dates line up with downtown's winter calendar:
- Nov. 1: The Town's winter overnight parking ban starts.
- Nov. 2: South Cache closes from Broadway to the alley for about 10 days.
- Nov. 20: WYDOT's target for finishing the concrete around the Millward signal corners.
- Nov. 21: Active construction, detours and intersection closures are scheduled to end for the winter.
- Dec. 3: The 15th Annual Wort Plaza Street Lighting on North Glenwood.
- Apr. 15: The overnight parking ban ends.
- Spring 2027: Crews return for Broadway slab repairs and the remaining bulb-out corners.
- June 15, 2027: Anticipated completion of the whole project.
Winter downtown, between the two seasons of work
When the construction rules lift, the winter rules are already in effect. Jackson's overnight street parking ban runs Nov. 1 to April 15 and prohibits parking from 3 a.m. to 7 a.m. The Jackson Hole News&Guide reported that it's enforced every morning and that vehicles may be towed if snowplows need to get through. For about three weeks, the construction parking restrictions on Broadway and Cache and the overnight ban overlap. After Nov. 21, only the overnight ban is left.
The first big downtown evening after the pause happens a block off Broadway. The Jackson Hole Chamber of Commerce lists the 15th Annual Wort Plaza Street Lighting for Thursday, Dec. 3, 2026, from 5 to 7 p.m. at The Wort Hotel, 50 N. Glenwood St. Santa arrives at 6 p.m. to help switch on the lights, and there's live music, cookies and cocoa, followed by a 21-and-over bar event from 7 to 11 p.m. Glenwood is one of the three Broadway intersections crews worked on this fall, so people walking over from the Square that night will cross a street that was a work zone a few weeks before.
For questions about the work before it pauses, the Town takes them at [email protected]. The Town also says it posts real-time construction updates on the Waze app. WYDOT posts its own updates through its Jackson Facebook page and the WYDOT 511 announcements page.
At Mountain Group, we pay attention to how projects like this change the blocks we walk every day, from the corner at Millward to the new curbs on Glenwood.
