Underground Utility Installation Continues and Storm Drainage Improvements Begin

Construction crews are mostly complete with the underground infrastructure that will house the overhead power and communication lines. Next up will be coordinating with Nevada Energy, ATT, and Charter to populate the underground conduit and work on re-supplying service to adjacent properties through the newly installed improvements. Construction of the storm drainage improvements is also underway. Inlets are being added between Carson and Roop so that water no longer needs to run a long distance in the curb before entering the underground storm drainage system. Water and sewer system improvements will be underway soon!

UPDATE – 8/26/2025

Underground Utility Installation Progresses on William Street

Construction crews are currently installing underground conduit to relocate overhead power and communication lines along William Street. The contractor has completed the primary conduit run from Carson to Roop Street and is now extending the system toward Saliman Street. These conduits will accommodate NV Energy power lines as well as Charter and AT&T communication infrastructure.
This undergrounding initiative represents a key step in modernizing the William Street corridor and advancing the city's vision of creating an integrated Complete Streets network. The utility relocation phase is scheduled for completion by mid-October 2025, with Complete Streets improvements beginning concurrently in early September.

BACKGROUND

Project History

The Nevada Department of Transportation (NDOT) transferred East William Street to Carson City after the completion of the I-580 Freeway. Prior to the freeway, East William Street was a state highway (US Highway 50) serving as a major roadway to move vehicle traffic quickly through Carson City. The current roadway is wide, with traffic moving at higher speeds, and there are few bicycle or pedestrian amenities. In some sections, there are no sidewalks. While traffic has decreased since the completion of the freeway, crashes have increased. Blocks are long, and intersections with protected pedestrian crossings are infrequent. The result is a vehicle focused corridor with only minimal accommodations for pedestrians and bicyclists.

CONNECTING-WITH-THE-CAPITAL Now under Carson City ownership, City planners and engineers are working to transform the corridor between N. Carson Street and the I-580 interchange from a vehicle dominated thoroughfare to a destination roadway shared by all users including drivers, cyclists, and pedestrians; otherwise known as a Complete Street.

Carson City has officially launched the East William Street Complete Street Project, a comprehensive infrastructure upgrade spanning the corridor from Carson Street to I-580. This major initiative represents the fourth corridor revitalization project funded through the 1/8th cent sales tax approved by voters in 2014, following the successful completion of Downtown Carson, Downtown Curry, and South Carson Street projects.

The East William Street Project encompasses a complete transformation of the corridor infrastructure, beginning with the relocation of overhead utilities underground from Carson Street to Saliman Road. Aging water and sewer systems throughout the corridor will be completely replaced to provide enhanced reliability for properties and businesses in the area. New storm drain infrastructure will be installed to improve drainage and treat stormwater runoff, addressing drainage concerns along the corridor.

Transportation and accessibility improvements will include the replacement of deteriorated sidewalks and driveways, the addition of dedicated bike lanes, and the construction of new sidewalks and multi-use pathways to improve connectivity for all users. Traffic signal upgrades will be implemented throughout the corridor, along with enhanced street lighting and comprehensive landscaping to create a more attractive and functional streetscape.

Construction is expected to continue through mid-summer 2026, with varying levels of traffic and access impacts anticipated as different phases are completed. The construction approach will progress from west to east, with the most significant construction activities concentrated at the western end of the project corridor.

Throughout the construction period, residents and visitors are strongly encouraged to continue supporting local businesses along the East William Street corridor. The construction team is committed to maintaining property and business access throughout all phases of the project while completing this major corridor upgrade that will enhance infrastructure, connectivity, and quality of life for the Carson City community.

East William Street Neighborhood Improvement District

Information on maintenance standards and NID assessments for the City’s two existing Improvement Districts can be found at the planning-division.

The Carson City Board of Supervisors enacted a one-eighth-percent sales tax in 2014 to help fund improvements to the City’s primary commercial corridors, including the East William Street project. The approved Plan of Expenditure for the sales tax included a provision that an assessment district would be formed as part of each corridor project to contribute funding annually to the city to provide for routine maintenance required for the corridors such as cleaning sidewalks, maintaining landscaping, servicing trash receptacles, etc. Such a district was formed for the maintenance of the Downtown Carson, Curry Streetscape, and South Carson Projects constructed in 2016, 2018, and 2020. All three were funded by Neighborhood Improvement Districts (NIDs).

The formation of a NID can provide the following benefits:
• Increase in property values
• Attract new businesses and visitors to the corridor
• Sustainable and dedicated funding to ensure quality maintenance and preservation of infrastructure and roadway beatification improvements

All the planned street corridor projects are designed to improve each corridor segment by: (1) enhancing business access; (2) increasing safety through lighting and roadway improvements; (3) improving pedestrian access and connectivity; (4) adding bike lanes; and (5) enhancing aesthetics through parkway landscaping and streetscape improvements. All such improvements have been proposed in an effort to make the corridors more inviting to the public and thereby increase the attractiveness of the local businesses located along the corridors, which will increase the City’s economic vitality.

The East William Street Project is designed with the intent to meet all the strategic objectives listed above. The project’s purpose is to convert the East William Street corridor into more productive uses that facilitate comfortable, convenient, and safe travel for pedestrians and cyclists; improve access to abutting businesses; spur private investment in this important and vibrant commercial corridor; increase driver safety; as well as create a more aesthetically pleasing and inviting gateway into our City. The overall project will include complete streets improvements from Carson Street to the I-580 Freeway, as well as significant upgrades and expansion to critical utility infrastructure along the corridor.

FAQS

FAQ: EAST WILLIAMS COMPLETE STREETS PROJECT

The first step to the complete street transformation of East William Street is the completion of a Feasibility Study to determine what improvements can be made. The Feasibility Study will examine features including safety, beautification, traffic operations, and bicycle and pedestrian enhancements. The Feasibility Study limits begin at North Carson Street and continue east to the interchange of I-580, approximately 1.5 miles. During the Feasibility Study, the engineering team will also evaluate utility and stormwater improvement needs throughout the corridor to accomplish a “dig once” approach.
