In the late 1800’s, the city of Roanoke, VA was built on marshy land previously known by travelers as a large area of salt licks abundant with wild game for the hunting. As part of the city’s construction, spring fed Trout Run was completely enclosed in a tunnel and a section of the city built on top. The original tunnel roof, constructed of wood, was quickly found to be rotting and replaced with brick in the early 1900’s. Since then, numerous sections of the tunnel have had to be repaired and replaced over time.
Gilmer Avenue in NW Roanoke runs over Trout Run and that section of roadway is supported by a cast in place concrete bridge, constructed in 1932. By 2010, the bridge over Trout Run was deemed structurally deficient and plans were made to replace the bridge with precast concrete box culvert.
CP&P’s Salem facility produced 26 pieces of 14’ wide by 6 ½’ high (inside) precast concrete box culvert sections, designed for 0’ to 2’ of cover. The design requirements included the use of Corrosion Resistant Reinforcing. Installation of the boxes proceeded smoothly by the experienced team at Burleigh Construction Co.
