Last Updated: November 11, 2014

Newsletter July 1, 2014


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 4.0

Construction of the foundation and support elements is completed and riprap is being installed. The bridge girders have been set and the contractor is installing the forms for the concrete bridge deck to be poured.

Concrete abutment walls and girders support the bridge superstructure (deck). Riprap is placed to help prevent further erosion.

Bridge Structure 6.1

Construction of the foundation and support elements is complete. Concrete girders have been placed and the contractor will begin placing forms to pour the concrete bridge deck..

Precast concrete girders are set in place with a crane. Once this is complete the contractor will begin working on the forms for
the concrete bridge deck.

Bridge Structure 8.0

Concrete caissons, abutment footings and walls and placement of girders have been completed and the contractor has poured the concrete bridge deck. Further work on this bridge will wait until the concrete meets specified strength requirements.

The contractor has poured the concrete bridge deck. Periodic tests will be run on concrete samples taken during the pour to
determine when concrete has met specified strength.

CR 27 "Narrows"

Production blasting is complete and "clean-up" blasting will be taking place over the next few weeks. Rock excavation, embankment and riprap placement continue in the "Narrows". The Contractor is installing two precast concrete box culverts in this section. Work continues 7 days a week.

Precast concrete box culvert sections will be installed in the "Narrows"

Riprap material is placed to help prevent further erosion of the slopes.


Repairs to this road began in June, 2014. Opening of the road to through traffic is scheduled for December of 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%.
