General Project Narrative: The existing single span 22'-4" bridge over Caudle Branch on SR 1408 (Deep Springs Rd) is being replaced with a single span (1 @65') 24" cored slab bridge. The bridge will be

Quality Impacts) patterns will be maintained. There are roadside ditches that flow towards the bridge on either side of the structure; however, near the bridge site they flow away from the
roadway and into a floodplain. The existing ditches will be maintained. There are no proposed ditches. Toe protection will also be used on proposed fill slopes where overland
flow occurs along the toe of the fill slopes. On the begin side of the bridge, a tra�c bearing 2G1 drainage inlets was placed on the low side of the superelevation to pick up runoff
from the bridge. Class-II rip rap abutment protection on both banks of the stream is also proposed to prevent future erosion and stream migration.
