I-15 ‘Technology Corridor’ rebuild tops UDOT’s Top 10 projects in 2018

The Utah Department of Transportation (UDOT) will oversee work on 188 highway projects throughout the state this year. Projects will range from sidewalk and streetlight installations to the rebuilding of a 12-lane section of freeway in Utah County. The price tag? UDOT sets the value of its ongoing and planned projects for the year at $1.46 billion.

The agency also named the Top 10 projects, which include widening and rebuilding freeways, constructing new interchanges or redesigning existing ones and repaving and upgrading other local and regional highways. Several of the projects will continue beyond 2018, UDOT said.

Listed as UDOT’s Top 10 projects for 2018 are:

1. I-15 Technology Corridor. Utah County, S.R. 92 to Lehi Main Street, $450 million. The project is scheduled for a spring start to widen I-15 to six lanes in both directions between S.R. 92 (Timpanogos Highway) and Main Street in Lehi. This is the last remaining section of I-15 between Salt Lake City and Spanish Fork where the freeway is still only four lanes wide. The project will finish in late 2020.

2. I-15 Southbound. Salt Lake County, 2100 South to 12300 South, $180 million. The project will widen I-15 in Salt Lake County by adding a new southbound lane from 2100 South to 12300 South. Also included is the redesign of some of the southbound ramps at the I-15/I-215 south interchange to improve traffic flow and towiden 7200 South to three lanes from I-15 to Bingham Junction Boulevard in Midvale. Work is expected to be complete in late 2019.

3. I-215/Redwood Road Diverging Diamond Interchange. North Salt Lake, $40 million. Crews will reconstruct I-215 from the I-15 interchange in North Salt Lake to 2100 North and construct a new diverging diamond interchange at Redwood Road and I-215. Construction started in February and will continue through the end of the year.

4. I-80/S.R. 36 Bridge Replacements. Tooele County, $30 million. UDOT will replace three bridges on I-80 near the S.R. 36 interchange of eastbound and westbound I-80 over the Union Pacific railroad tracks and the S.R. 36 ramp bridge. Construction on these bridges will start in later this  spring and is expected to be complete in summer 2019.

5. Bluff Street. St. George, $51 million. UDOT is widening Bluff Street in St. George from 100 South to Sunset Boulevard. Crews will add a lane in each direction and add turn lanes at several intersections. This project started in January and will continue for about 12 months.

6. I-80. Parleys Canyon, $30 million. I-80 will be widened to add a new westbound lane for trucks from Jeremy Ranch to Parleys Summit and a new wildlife crossing at the summit. In addition, crews will repave the interstate from Lambs Canyon to Kimball Junction. Construction started last week and is scheduled for completion by the end of the year.

7. Mountain View Corridor. Utah County, $41 million. Mountain View Corridor in Utah County will be extended from the Redwood Road/2100 North intersection to S.R. 73. Work also begins later in the spring and will finish in 2019.

New interchanges are under construction at 5400 South, 7000 South, 9000 South and 11400 South and are scheduled to be completed by the end of the year.

9. S.R. 9. Springdale, $19 million. Crews are reconstructing S.R. 9, the gateway to Zion National Park, through the town of Springdale. Workers are removing the old pavement and replacing it with new asphalt and adding new pedestrian and bike improvements.
