Work Begins on WY 70 Slide
Work begins next week building a new, permanent roadway realignment to circumvent a slide that destroyed a section of WYO 70 between Baggs and Riverside in south-central Wyoming. The damage, which was discovered by a snowmobiler on May 30, 2011, is 600 feet long and located just west of the overlook at mile post 30.
Spokesman Ross Doman says A temporary detour around the slide was completed in mid-July last year. It has served traffic through the area since then, except for the period last winter when the alpine roadway was closed for the season.
The new roadway realignment will be constructed several hundred feet up the hill above the slide, as recommended by WYDOT geologists due to better ground stability. Final dirt grade and placement of crushed base is scheduled to be completed this year by Oct. 31. Traffic may be shifted onto the new road at that time, depending on the weather. The new road will be paved and completed next year during construction season.
Until the new road realignment is ready for traffic, travelers will continue to be routed through the detour. It is a single-lane dirt road with a gravel surface that operates as one-way alternating traffic. Restrictions through the detour section are 30,000 pounds gross vehicle weight and under. A ten foot width maximum is being enforced and long loads are discouraged.
The one mile section of new roadway will cost $2.8 million. The contractor is High Country Construction out of Lander and the work is federally funded.
