Access Roads

Larimer County Access Road and Bridge Nearly Complete

The Larimer County access road bridge crosses over the Colorado-Big Thompson (C-BT) Project’s Bald Mountain Penstocks above Flatiron Reservoir. The bridge will provide reservoir construction access during the next three to four years before becoming part of the entry road to Chimney Hollow’s future public recreation and open space facilities.  

The bridge – made up of 14 concrete sections that each weigh 52,000 pounds – was manufactured off-site by ConTech Engineered Solutions. Sterling Crane, the subcontractor hired by Barnard Construction Co. Inc., safely installed the bridge in one day, demonstrating well planned and executed construction. In addition, the intersection of the new access road and Larimer County Road 18E will be upgraded to include dedicated turn and merge lanes to improve safety and reduce local traffic impacts.

Saddle Dam Access Road

The saddle dam access road will provide vehicle access to the crest of the saddle dam and the Western Area Power Authority powerline. The saddle dam road will connect the end of the Larimer County access road to the saddle dam for Northern Water maintenance access. The road incorporates the construction roads built as part of the WAPA transmission line relocation project. This road will not be open for public vehicles.
