Location: The proposed bank protection project [Job Piece 28969(04)] is located at 7600 OK-10, along SH-10 Highway in Section 5, Township 18 North, Range 23 East, on Illinois River, Cherokee County, Oklahoma. The project site can be found on the Tahlequah, Oklahoma 7.5 Minute USGS Quadrangle map at North Latitude 36.069403 and West Longitude 94.880902.

Purpose:  ODOT, in cooperation with the Federal Highway Administration (FHWA) states the purpose of the proposed project would provide long-term fortification protection and prevent bank failure along this reach of SH-10. The river has caused bank instability along the embankment and threatens the safety of the highway. The overall purpose of this work is to bring this portion of SH-10 Highway in compliance with the Federal Safety Slope Standards to ensure the proposed improvements correct roadway deficiencies, efficiently accommodate traffic, enhance public safety and efficient traffic flow.

Description of Work:  The applicant proposes the placement of dredged or fill material consisting of concrete (588 cys) for construction of the soldier pile wall for approximately 1,730 lf. The soldier pile wall would be approximately 2.5 wide ft and the wall height would vary approximately 6 ft to 15 ft high and would be in the form of panels held in place by vertical piles. The permanent impacts for the soldier pile wall totals 0.65 ac (1,777 lf). The applicant also proposes the placement of dredged or fill material using 3,152 cys of 3-in rock riprap. Additionally, various sizes of rock totaling 344 cys ranging from approximately 1-in to 12-in that would be used to backfill behind the proposed soldier pile wall.

The applicant proposal includes placement of dredged or fill material totaling 0.04 acre (379 lf) of permanent impacts for the construction of the gabion baskets. The backfill material for the gabion basket (totaling 90 cys and riprap totaling 50 cys) would be placed in open water within the unnamed tributary of Illinois River at the upstream end of the project.

The applicant also proposes the placement of dredge or fill material consisting of 0.05 acre (26 lf) using gabion baskets (34 cys) as permanent impacts to protect the unnamed tributary of Peavine Hollow Creek at the downstream end of the project.

The applicant proposes to construct a temporary work platform approximately 25-ft wide using 1.44 ac (approximately 2,465 lf total length). This platform would consist of the placement of dredged or fill material using various rock riprap totaling 8,310 cys and 3-in rock totaling 2,651 cys. Approximately 10,961 cys would be used riprap for backfill. The temporary work platform is approximately 1,801 lf in Illinois River.

The temporary work platform would be held in place with gabions baskets and 3-inch stone backfill placed along the surface of the work platform within geocell mats, which would be anchored into the gabion basket wall. The separator fabric, and geocell matt would be installed from Sta. 12+20 to Sta. 904+70. The purpose of the geocell mats is to provide a solid work platform for the construction vehicles and to keep the rock in place. The rock and stone used for the proposed platform would likely be limestone rock sourced from the region. A floating buoy system would be along the proposed work platform. The buoy would be held in place at the edge of the construction area by a chain laid on the riverbed and anchored into the work platform. A rope would connect the chain to the bottom of the buoy. All temporary fill materials and the buoy system would be removed following construction.

The work would be performed using conventional earthmoving equipment for excavator, wheeled dump trucks and track equipment.
