With another legislative session in the books, lawmakers have again given state officials more control over Salt Lake City’s streets.

This time, lawmakers set permanent rules for how, when and where City Hall can redesign its notoriously wide roads to slow down traffic, make them safer for pedestrians and promote other forms of transportation.

SB242, written by Sen. Wayne Harper, R-Taylorsville, passed both chambers on Friday, the last day of the general legislative session, after stalling in a committee hearing earlier in the week.

In the House, some suburban Democrats joined the bulk of Republicans in a 55-14 vote to pass the bill. Back in the Senate, 19 Republicans voted in favor, while Utah County’s Republican Sen. Heidi Balderee, Republican Sen. Brady Brammer and Forward Party Sen. Emily Buss joined the chamber’s six Democrats in opposition.

The legislation now awaits Gov. Spencer Cox’s signature, which would make it law.

Harper’s bill forces the city and the Utah Department of Transportation to come to an agreement to guide street redesigns in most of Utah’s capital. Here’s what has to be in that pact:

• A four-tier classification system for the city’s roads with Tier 1 including the busiest ones, like 800 South, and Tier 4 denoting quiet neighborhood avenues.

• A ban on any project that reduces traffic capacity or removes lanes on a Tier 1 road.

• UDOT veto power over projects that include safety improvements or traffic-calming measures on Tier 1 and Tier 2 streets.

• A rule that the city must consider on-street parking when planning projects on Tier 1 and Tier 2 roads

• Plans showing how the city will ensure traffic flows, emergency vehicles are not slowed, and businesses remain accessible where traffic-calming measures were either installed or are under construction on 200 South, 400 South and 300 West.

• A ban on lane widths less than 11 feet on Tier 1 and Tier 2 roads and less than 10 feet on Tier 3 streets.

Harper and other proponents say the legislation is necessary because residents from across the state visit Salt Lake City. UDOT, he contends, should have input on City Hall’s streets projects.

The bill encountered vocal opposition from residents, many of whom were supportive of efforts to make streets safer and worried that it would slow down or even halt such improvements.

The wide-ranging legislation, known as an omnibus bill, also addresses other statewide transportation issues. If signed, it would:

• Allow a city or a county to temporarily ban mobile businesses from a street closed for an event.

• Affix a road user charge to commercial electric vehicles over 6,001 pounds.

• Let buses on fixed routes cross over bike lanes to make stops.

• Provide a sales tax exemption on some materials purchased by UDOT for public transit projects.

• Open state funds for use in rail repair projects and authorize bond funding for the FrontRunner double-tracking proposal.

• Earmark money for some suburban Salt Lake County road projects.

• Require towing companies to have an online presence.
