Description

THIS IS NOT A REQUEST FOR BID PLANS AND SPECIFICATIONS ARE NOT AVAILABLE.

PROJECT NUMBER: UT FLAP 73(2)

PROJECT NAME: LaSal Loop Road

The UT FLAP 73(2) LaSal Loop Road project is located approximately 8 miles southeast of Moab, UT in Eastern Utah. The project crosses through Utah State School and Institutional Trust Lands (SITLA), Bureau of Land Management (BLM), private, and United States Forest Service (USFS) lands, providing access to the Manti - La Sal National Forest and Bureau of Land Management lands. The route is categorized as a major rural collector in mountainous terrain and is maintained by San Juan County.

This project rehabilitates and reconstructs the existing road with minor superelevation correction, profile adjustments, curve widening, ditch reconstruction, culvert replacements, asphalt surfacing, erosion control, signing, and pavement markings. The existing pavement is in poor condition with significant rutting, cracking, and potholing apparent along the route. To complete the proposed widening and realignment, rock and soil cuts and fills are expected. Due to the mountainous terrain, significant boulders and areas with noted seepage or soft subgrade will be encountered. The project consists of two segments, broken into Schedule A and Option X.

Segment 1 (Option X) - Segment 1 goes from the intersection of Old Airport Road 11 +62 to 147+00 at the intersection of Pack Creek Cutoff. Rehabilitation and widening consists of pulverizing the existing pavement, widening the road to 30 feet from the beginning to 45+00 and 26 feet for the remainder of the road, placing aggregate base and asphalt concrete pavement, and drainage improvements.

Segment 2 (Schedule A) - Segment 2 goes from 147+00 at the intersection of Pack Creek Cutoff, and goes to 650+91, the boundary with the previous project UT PFH 46-1(2) and UT FLAP 73(1). Rehabilitation consists of pulverizing the existing pavement, placing new aggregate base leveling, asphalt concrete pavement, and drainage improvements to narrow the roadway width to 26 feet. Five locations will be reconstructed requiring raising or lowering profile, placing aggregate base, asphalt concrete pavement, and drainage improvements to widen the roadway width to 26 feet.

It is anticipated this project will be advertised in October 2023 and be under construction in January 2024. The project has a completion date of October 22, 2025.
The estimated price range of the project work is between $20,000,000 and $30,000,000.

MISCELLANEOUS:

Construction will take two construction seasons to complete. The project ranges in elevation from 4870 feet at Station 11 +62 to a maximum elevation of 7,960 near Station 616+00. Construction along the entire alignment may not be always favorable during the construction duration, generally limiting operations sensitive to snow and seasonal cold temperatures at higher elevations during autumn, winter, and spring months (October to April).

Due to environmental considerations, Station 545+00 to 651 +00 must be completed between May 2024 and October 2024.

This will be advertised as a full and open competition.
