Chip sealing is scheduled to start Tuesday, June 23, on the $8.77 million section of improvements being made to U.S. Highway 14-16-20 west of Wapiti. Weather permitting, prime contractor Riverside Contracting, Inc., will start after 10 a.m. on Tuesday and finish by Thursday, June 25, said Wyoming Department of Transportation resident engineer Todd Frost in Cody.

The project covers 4.26 miles of the highway, running from the Wapiti bridge (milepost 31.98) over the North Fork of the Shoshone River to just east of the Shoshone National Forest boundary (milepost 27.72).
"This piece of highway has been widened from the old 12-foot lanes and six-foot shoulders to 12-foot lanes and eight-foot shoulders, and shoulders were flattened to improve safety," Frost explained. "Existing pipes and box culverts were in poor condition and have been replaced, and drainage has been improved."
Meanwhile, as that work wraps up, Riverside Contracting is beginning another $3.45 million in highway improvements directly east of Wapiti (the Wapiti East project).
The new project starts at the North Fork of the Shoshone River bridge at Wapiti and goes to just east of the Trout Creek bridge (near the Wapiti post office) on U.S. 14-16-20. Frost said the contractor is tentatively scheduled to begin dirt and pipe work on Monday, June 22.
Other than several pipe crossings across the highway, the highway surface will remain as asphalt through the duration of the project.

Frost said the project also includes deck repair and an epoxy deck overlay to the North Fork bridge, and the Trout Creek bridge will have approach slab replacement and a silica fume deck overlay. Bridge rehabilitation depends upon favorable temperatures, so it is important it is completed during the summer, Frost said.
WYDOT's contract with Riverside calls for maximum traffic delays of 15 minutes and work will stop July 1-5.
Flaggers and a pilot car will be used to control most of the traffic, with traffic signals controlling vehicles as they cross the bridges, which will be reduced to one lane during the project.
The Wapiti East project consists of a one-inch asphalt pavement leveling, a two-inch pavement overlay and a chip seal, with some minor slope flattening and some pipe replacement and bridge rehabilitation. It covers 4.45 miles of U.S. 14-16-20, from milepost 31.98 to milepost 36.43, between Yellowstone National Park and Cody. The contract calls for the work to be completed by Sept. 30, 2016.
