Smith River Curve Improvement Project

Smith River Curve Improvement Project

The proposed project would widen a portion of the roadway to improve safety at a nonstandard curve location from post mile 8.2 to 8.3. The improvement at this curve location would create a facility with two 12-foot lanes and 8 foot shoulders by realigning the roadway, and constructing a 22-foot wide, approximately 220-foot-long side-hill viaduct to support the curve widening. The widening would occur primarily on the northbound lane of the roadway to reduce the extent of cutting the steep slope adjacent to the existing roadway. The viaduct foundation would be constructed of cast-in-drilled-hole (CIDH) piles that would be installed into rock at each bent and abutment. A total of 16 piles would be installed. No portion of the proposed structure would be located in or extend over the river.
