Project Overview

The Utah Department of Transportation (UDOT), in partnership with the Capitol Preservation Board (CPB) and the Utah Division of Facilities Construction and Management (DFCM), is building a new, single-lane roundabout at State Street and 300 North in Salt Lake City, in front of the Utah State Capitol building.

The roundabout is designed to enhance safety at this busy intersection for all users.

In coordination with the roundabout project, the DFCM is relocating the State of Utah wall to allow more space for gatherings and photography opportunities. These efforts will combine to create a welcoming environment for residents and Capitol visitors.

Roundabout Opening Soon

The roundabout is expected to fully open to traffic by early January 2025, in conjunction with the completion of the State of Utah Wall construction.

By the end of the day on Tuesday, Dec. 17, a portion of the roundabout will open to drivers heading eastbound on 300 North to southbound State Street, as shown in the map below. No other movements will be available until early January.

Please drive slowly and carefully in the area, and observe all posted detour signage. East Capitol Street, 300 North, Hillside Avenue and 200 North remain local traffic only routes. The following detours remain in effect for closed movements through the State Street and 300 North intersection:

Pedestrian Information

The work zone will be fenced off and inaccessible to pedestrians and cyclists. Please obey all posted signage and do not enter the active work zone. Crosswalks east and west of the intersection will be available.

The southeast sidewalk will close on Oct. 3. Pedestrians should follow the posted signage and use the southwest sidewalk while the closure is in place. 

State of Utah employees and Capitol visitors should access campus buildings by using the routes shown in the map below.

Transit Information

UTA's 200 bus line will have a modified route for the duration of construction. The bus will travel north on Main Street, stop on the west side of the Capitol, and return to the downtown area via Main Street.

For real-time information and details on routes, we recommend calling UTA at 801-RIDE-UTA (743-3882). Paratransit and community resources are also available.
