WY HPP 4-1(6), Beartooth Highway (U. S. 212)

Added: Apr 16, 2010 9:20 am Modified: Apr 19, 2010 11:38 amTrack Changes This project will be advertised on an unrestricted (full and open) basis.



PROJECT DETAILS: The Beartooth Highway in Wyoming begins at the Wyoming/Montana State Line east of Cooke City, Montana, following US 212 for 56.1 kilometers to the Wyoming/Montana State Line southwest of Red Lodge, Montana. The project is located entirely within the Shoshone National Forest. The project begins at approximately Mile Post 26 immediately west of Beartooth Lake Outlet Bridge, and ends at approximately Mile Post 27.7 immediately west of Little Bear Creek. The project is located in remote, environmentally sensitive high alpine terrain (in excess of 9,000 feet) with a very limited construction season (4 to 5 months per year), and must be completed in 2011. Considerable attention to detail is required in project construction due the historical eligibility of the existing roadway and bridges.



The base schedule, Schedule A, for this project consists of the removal of the existing Beartooth Lake Outlet Bridge, and reconstructing a new structure, with approaches totaling 0.4 mile, immediately adjacent to, and partially over, the existing bridge. The existing bridge can be partially used for maintenance of traffic, and is required to be deconstructed in an extremely careful manner in order to preserve the existing stone masonry for reuse on the new structure, and limit turbidity in Beartooth Creek. Schedule A will also contain the construction of a historic bridge interpretive site, parking area, and access trail, as well as reconstruction of the Beartooth Lake Campground approach road intersection. The principal work items on the base schedule include: lump sum contractor testing, lump sum construction schedule, 3,500 m3 roadway excavation, 7,700 m3 unclassified borrow, 6,000 t aggregate base, 1,350 t superpave pavement, 124 m precast, prestressed concrete girders, 46,750 kg reinforcing steel - epoxy coated, 260 m3 structural concrete, 830 m micropiles, 2 trial micropiles, 131 m of Guardrail system G3 - Wyoming box beam steel posts, along with associated traffic control and equipment/flagging, soil erosion control, survey and staking, pavement markings.



There are two optional schedules: (1) Option V pre-grubbing removal of stumps, seeding and mulching, and erosion control, along a 1.2 mile extension of the eastern bridge approach; (2) Option W grade, drain, and pave 1.2 miles of roadway predominately along the existing alignment east of the Beartooth Lake Campground approach intersection.



Principal work items on Option V include: 200 hours each of Dump Truck, Bulldozer, Excavator, and Labor for stump removal, 4.0 ha seeding, 4.0 ha mulching, 2,400 m silt fence, and associated traffic control equipment/flagging, seeding, and mulching.



Principal work items on Option W include: lump sum contractor testing, lump sum construction schedule, 27,500 m3 roadway excavation, 5,100 m3 unclassified borrow, 14,000 t aggregate base, 3,650 t superpave pavement, 1,450 m asphalt curb, 450 m of guardrail system G4 (w-beam steel posts), 5.4 ha seeding, 4.6 ha mulching, along with associated traffic control and equipment/flagging, soil erosion control, survey and staking, pavement markings.



It is anticipated that this project will be advertised in early May with construction beginning in 2010 and extending up to two construction seasons.



Estimated cost for the base schedule and both options is $5 - $10 million.
