PROJECTS

SHERIDAN BUFFALO

This project involves resurfacing and 2 major slide repairs on 5.21 miles of Interstate 90 beginning at mile post 40.12 between Sheridan and Buffalo, Wyoming. The original contract amount was $19,183,206.40 and was awarded to Oftedal March 15, 2007. Work began on the job last spring (2007) and the majority of the grading work (slide repairs) and resurfacing of the west bound lanes was completed during that year. With extraordinary amounts of spring snow delaying the project initially, much of the work was accomplished utilizing a double shift. Thanks to these efforts (and a relatively mild fall), the paving work was completed prior to winter shut down.

MORAN JUNCTION - DUBOIS ROAD (BROOKS LAKE SECTION)

In January of 2006, WDOT awarded Oftedal a two year contract to reconstruct a 13.5 mile section of US 287 between Moran Jct. & Dubois, WY. When complete, Oftedal will have self performed the excavation and grading of 1.5 million CY of earth, processed over 300,000 tons of crushed base and 170,100 CY of sub base,  installed over 5 miles of pipe and culvert ranging from double cell 10' x 10' reinforced concrete box culverts to 24" corrugated metal drain pipe, constructed four geogrid reinforced fills and repaired four slide sections situated in steep, rugged terrain.

COUNTY LINE WEST (I-25 RECONSTRUCTION)

Reconstruction of a five mile section of I-25 in Converse and Natrona counties required widening both the north and south bound lanes, filling median ditches and recontouring shoulders. Oftedal placed over 900,000 CY of material using scrapers, haul trucks, and belly dumps.
