May 2025 update

The intersection at Center Street is now open and construction at the intersection is complete. The remaining speed humps on 500 North and 300 North will be installed after the school year ends to minimize disruption.

Overview

Salt Lake City, in partnership with the Capitol Hill Neighborhood Council, is moving forward with the next phase of the Capitol Hill Neighborhood Traffic Calming Plan—a community-driven effort developed over nearly three years. Shaped by extensive input from residents, the plan addresses long-standing concerns like cut-through commuter traffic, loud exhibition driving, and industrial vehicle traffic. These issues impact safety, comfort, and quality of life by increasing noise, air pollution, and overall street stress.

Building on the 58 speed humps installed in 2023, new improvements are planned for 2025 in the Marmalade/West Capitol Hill neighborhood:

Permanent upgrades at 600 North, 200 West, and Center Street
Following a successful 2021 “quick build” installation at this key gateway, the City will make the design permanent with curb extensions to shorten crossings, narrower vehicle lanes to reduce speeds, and improved sidewalks and crosswalks for people with mobility limitations.

Nine new speed humps
Additional concrete speed humps with a smoother profile will be added across the neighborhood (see map). The current hump at 600 North and 250 West will be replaced with two gentler humps to improve drivability while maintaining traffic calming.

In 2021, thanks to sponsorship and collaboration with our friends at SPIN scooters and through Capital Improvement Program (CIP) awarded funds; the Capitol Hill Neighborhood Council, with the help of neighbors and transportation gurus, implemented a quick-build at the intersection of 600 North and 200 West with the goal to calm traffic entering the neighborhood and improve safety for people walking and bicycling. The actual temporary design is part of the public input process for the neighborhood traffic calming initiative.
