SCOPE OF WORK
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 2.0Traffic is one lane over the bridge to allow crews to work on extending the northwest wingwall, backfilling and placing grouted riprap. Crews are also working on installing riprap on the upstream portion of the bridge. After work is complete on the northwest wingwall the one lane traffic will be switched to the other side of the road to allow crews to perform the same work on the southeast wingwall.
Bridge Structure 4.0The structure is now open to traffic with the majority of the superstructure construction complete, including bridge rails. Crews are currently working on installing permanent fence and guardrail crews will begin work here soon.
Bridge Structure 6.1
This structure is also open to traffic with the majority of the superstructure construction complete, including bridge rails.
Bridge Structure 8.0
Traffic is over the bridge here as well. Crews are currently installing riprap armoring 0.4 miles downstream from the bridge, working upstream. There will be three new 24" RCP cross culverts 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. Three of the four 20x10 concrete box culverts have been installed with the fourth at Ohana Way scheduled for installation the first week of the February. 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 will continue this winter and into spring with paving tentatively scheduled for April/May, depending on weather conditions.
Repairs to this road began in June, 2014. Opening of the road to through traffic is scheduled for December 24,2014. 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%.
