The Buckhorn Canyon Road (AKA County Road 27) sustained a great deal of damage from the 2013 floods. The reconstruction consists of construction of three new bridges, repairs to one existing bridge, and reconstruction of 1.6 miles of roadway through the "Narrows". To accomplish the above work approximately 40,000 cubic yards of rock will be blasted and excavated, 30,000 cubic yards of riprap placed, 11,000 tons of base course and 10,000 tons of asphalt placed, and 2000 cubic yards of concrete poured.


Bridge Structure 2.1

Wingwall repairs and extensions are complete. Riprap has been placed and traffic can drive in both lanes over the bridge. Paving and guardrail improvements are expected to occur in late March or April.

Bridge Structure 4.0

The structure is open to traffic. Road base surfacing has been placed and paving of the approaches and bridge deck is expected in late March or April.

Bridge Structure 6.1

This structure is also open to traffic with the majority of the superstructure construction complete, including bridge rails. Road base surfacing is next and paving of the approaches and bridge deck is expected in late March or April.

Bridge Structure 8.0

Traffic is over the bridge here as well. Crews have installed riprap armoring 0.4 miles downstream from the bridge.. Three new 24" RCP cross culverts are being installed in this section along with a turf reinforcement mat and grouted riprap on the east downstream side of the bridge.

CR 27 "Narrows"

All of the narrows are now open to two-way public traffic on a temporary gravel surface while crews continue to work. All four 20x10 concrete box culverts have been installed. All of the blasting and soil nailing has been completed. Most of the rock scaling has been completed with some possible cleanup this spring after the ground thaws. Riprap armoring of the structures and road embankment is nearly complete. Road base placement and paving are tentatively scheduled for April/May, depending on weather conditions. Guardrail installation will follow the paving operations.


Repairs to this road began in June 2014. Opening of the road to through traffic is scheduled for December, 24th 2014. Construction will continue as weather allows through the winter and minor delays can be expected during the day. Final completion of the project is expected in the spring of 2015.

This project was awarded to the American Civil Constructors, Inc. for $15,455,279.00. FEMA will provide 75% of the funding for the project while the state Office of Emergency Management and the county will each provide 12.5%.
