2014 Rural Highway Project of the Year – AGC of Utah

The I-15; US-91 (1100 South) Interchange Project won the AGC of Utah – 2014 Award of Excellence:  Rural Highway Project of the Year.

This project reconstructed the I-15 and US-91 Interchange near Brigham City.  This entailed construction of a new structure over I-15 while maintaining traffic on the old structure, and reconfiguring the interchange from a diamond interchange into a diverging diamond interchange.

The project team consisted of:

  • Owner : UDOT Region 1 – Jace Mecham, Resident Engineer
  • RLW – PM Betty Purdie-Alvez,  CM Derek Harames
  • Subcontractors:  Staker Parsons, CVE, Deb Harper, Peck Striping, Rouser, BT Gallegos, and others.

 

The project had many challenges including starting 6 weeks late due to a UDOT hold up, 6 months of settlement for new fill in the area, constructing bridge embankment out of Geofoam,  and challenging phasing.  With the project being an A+B – bid number of days to complete, schedule was always critical.  Despite many issues encountered, the project opened 2 weeks early.

In order to get the project completed, a 56 hour closure of US-91 was required.  To avoid issues with weekend traffic to Logan for a game, UDOT shifted the days and times of the closure to start on Sunday morning and complete Tuesday afternoon (originally was from Friday night to Monday morning).  Everyone pulled together and paving, striping, signals, traffic islands, barrier and signing were all installed, road reopened to the new configuration.  This all occurred with no public complaints.

Most important was the safety record of this project:  No recordable accidents, no first aide incidents, and an average UDOT Monthly Work zone inspection score of 98.7.

UDOT and the public are very happy with the final project.
