PROJECT NUMBER: WY FLAP NAT 505 & BL 6409(1)

PROJECT NAME: Casper Mtn Cir Dr & Muddy Mtn Rd

PROJECT DESCRIPTION:

Minor widening/reconstruction and resurfacing, restoration, and rehabilitation (3R) project in Natrona County, Wyoming (approximately 8 miles south of Casper, Wyoming). The proposed project is 12 miles long, generally extending from the intersection of Casper Mountain Circle Drive and Hogadon Road to South Circle Drive, and then continues along Muddy Mountain Road and ends at the Bureau of Land Management (BLM) Campground Loop. The route is used primarily as residential and recreational access to Muddy Mountain and is on rolling terrain with survey elevations ranging from 7,425 feet to 8,292 feet.

Proposed improvements include one base schedule and 2 options:

• Schedule A: BLM Muddy Mountain Road improvements


• Option X: County Casper Mountain Circle Drive improvements (S-Curve and new pavement portion)


• Option Y: County Casper Mountain Circle Drive improvements (Full Depth Reclamation [FDR])

SCOPE OF THE WORK:

Both the Schedule and Options require coordination with the County and BLM during construction activities. Casper Mountain Circle Drive provides access to many private residences and Muddy Mountain Road provides access to campgrounds.

Schedule A:

Muddy Mountain Road is approximately 7.49 miles in length and is aggregate surfaced. The project improvements will rehabilitate and resurface the 4.55 miles of two-lane road and 2.83 miles of single lane aggregate surfaced roads. There are two segments of Muddy Mountain Road consisting of steep grades where new pavement is proposed. There will be four new parking areas, with two of the areas modifying existing parking areas. Additionally, there is a snow fence that will be replaced.

Option X:

The Casper Mountain Circle Drive segment is 2.33 miles are aggregate surfaced with proposed new pavement. The new typical section will consist of 11-foot lanes and 1-foot shoulders. Additional improvements include curve widening of an S-curve area, reconditioning ditches, adding culverts, and pavement markings and delineators.

Option Y:

Casper Mountain Circle Drive is approximately 2.65 miles of existing pavement is fatigued and nearing the end of its serviceable life with proposed FDR. Additional improvements include sub excavation, reconditioning ditches, adding culverts, and pavement markings and delineators.
