East William Street Is Almost Finished. Here's What Changes the Next Time You Drive It

Take the I-580 exit onto East William Street and head west toward downtown, and the road feels narrower than the one you remember. Part of that is the cones. When the cones come down, part of it will stay. East William Street is being rebuilt to drive like a city street, and when the last lane shift clears this month, that slower drive is the design working as intended.

Final paving between Roop Street and Russell Way was scheduled for Oct. 12 through 22, and Carson City Engineer Darren Anderson described it to Carson Now as "the last major step toward completing the project." After paving, crews move to striping, landscaping and minor finishing work, and the project is expected to be fully complete in November, weather permitting.

A highway the freeway left behind

East William Street used to be US Highway 50. It was a state road built to move vehicles through Carson City fast. Once I-580 was finished, the Nevada Department of Transportation handed the street over to the city. The city's East William Street project page describes what came with it: a wide roadway with higher-speed traffic, long blocks, few protected pedestrian crossings and stretches with no sidewalk at all.

The same page notes that traffic on East William dropped after the freeway opened, while crashes went up. Fewer cars were moving on lanes still sized for highway traffic. The rebuild is the city's answer to that, and every change below works by taking back some of the room drivers had.

Anderson told Carson Now in January that East William is "a gateway to the downtown Carson area." The finished street is meant to shift gradually from Highway 50 at the east end to the downtown streetscape at the west end. The same report noted the corridor's longer history. Before it was a busy state highway, it was a railroad route.

Where you'll feel it, block by block

Drive it from the freeway toward Carson Street and the changes come in this order, based on the design details Carson Now reported from the city's 2023 community meeting and later updates:

1. The east end, coming off I-580. The 35 mph zone moves farther east, so traffic slows sooner as it enters town from the freeway.
2. The whole corridor. Travel lanes shrink from 12 to 14 feet wide down to 11 feet, a change city engineers presented as a way to "naturally slow traffic speeds." Buffered bike lanes run the length of the corridor, with a three-foot buffer between bikes and cars. New medians block risky left turns across several lanes and give pedestrians a refuge at crosswalks.
3. Mills Park. A new crosswalk with flashers, more parking with EV charging stations, and an improved multi-use path near the park. The city lists a new 10-foot-wide multi-use path among the corridor improvements.
4. Saliman Road. The westbound right-turn lane goes away and the left-turn lane gets longer, to deal with traffic that used to back up there.
5. North Carson Street to Stewart Street. Eastbound drops from two lanes to one to make room for wider sidewalks and landscaping, and a traffic-calming median with dedicated turn lanes goes in where they apply.

The changes most likely to annoy a driver are the medians that end a familiar left turn and the single eastbound lane leaving downtown. Those are also the ones aimed most directly at the crash pattern the city described. New traffic signals and new street lighting run the length of the corridor.

Why it took a year of dirt to get here

Anyone who drove William Street in the past year mostly saw trenches, and the reason is that much of the rebuild went in underground before the surface could be redone. Carson Now reported that more than 40% of the project is underground. The city used a "dig once" approach, replacing water, sewer and storm drain lines before finishing the surface.

The plan moves overhead utilities underground from Carson Street to Saliman Road, with NV Energy's removal of the old power lines listed among the last utility milestones, and the city describes the new storm drain as a fix for roadway flooding. Utility conversion started in June 2025. Complete Streets construction started in November 2025, and repaving between Carson Street and Roop Street was finished in June 2026.

That order is why the street will look so different from the one it replaced. Once the power poles are gone and the sidewalks are continuous, the corridor has room for landscaping and the multi-use path.

Who paid for it, and what didn't make the cut

East William is the fourth corridor project funded by the one-eighth-cent sales tax adopted in 2014 to improve Carson City's main commercial streets. Here are the four in order:

The Nevada Appeal reported that the Board of Supervisors approved a contract with Granite Construction for about $22.5 million in May 2025, and that the project received a $9.3 million federal RAISE grant. Carson Now reported that most of the money comes from the sales tax.

Some requests didn't fit the budget. Staff said at the 2023 meeting that budget limits and federal grant requirements ruled out higher-cost ideas like a pedestrian bridge and a roundabout, according to Carson Now.

If South Carson Street gives you a preview, Anderson's own comparison fits. Carson Now quoted the city saying the public should expect improvements similar to the ones on S. Carson Street once the project is done.

The stops along the new street this season

A street built for walking only matters if there are places to walk to, and East William already has several worth the trip in the weeks right after the work ends.

Carson City Community Center, 851 East William Street. The Carson Christmas Creator Fairs are on the calendar for Saturday, Nov. 21, Saturday, Dec. 5 and Saturday, Dec. 12, each from 10 a.m. to 4 p.m., according to Visit Carson City.

Mills Park. The park runs alongside the corridor and covers 53 acres. In August, the Mills Park Pickleball Courts at 841 N. Roop St. added six courts, for 14 public courts in total.

444 E. William St. Mofos Pizza, a family business that started in Incline Village in 1986, plans to open its Carson City location here in the former Big Chicken space. The Nevada Appeal reported a target of late November or early December, with hours of 11 a.m. to 8:30 p.m., seven days a week, plus a salad bar alongside the pizza and pasta.

The long-standing corridor names. Gold Dust West, Saltwater Tavern, The Cracker Box and National's Café were among the businesses in the city's "Walk About William Street" campaign this summer. The campaign ran June 22 through July 20 and encouraged residents to keep shopping on William while construction narrowed the road.

The last few weeks, and the next street in line

As of the city's Oct. 28 update, traffic control for the week of Nov. 2 kept one lane open in each direction between Carson Street and I-580, 24 hours a day, with the north side of the Saliman intersection closed Tuesday through Thursday. For the final stretch, the most direct way to get closures is to text UPDATES to 775-227-1414. The weekly Road Report also runs on Carson Now every Sunday and in the Nevada Appeal's Saturday print edition.

The city has already started on the next corridor. Its North Carson Street project page opened a public survey on possible alternatives on Nov. 2, followed by an open house on Nov. 4. That work is at the feasibility and planning stage. Anyone who wants a say in how North Carson ends up can drive East William once the striping is down and see what the city built last time.
