The commission is recommending that the money be split among Little Cottonwood Canyon in Salt Lake County, Moab/Arches National Park, St. George/Zion National Park and the Bear Lake/Garden City areas.
The $100 million comes from a bill the Legislature passed this year to borrow $1 billion over four years to accelerate highway projects statewide.
The commission ranked projects based on congestion (67 percent of possible points), potential to improve economic development (18 percent) and increased recreation (15 percent).
Part of that proposal would include spending $2 million to start environmental studies needed for work in Little Cottonwood Canyon, and money for further evaluation of other projects, including $150,000 for the Zion/St.
