- 40’ (12 m) of 24” (600 mm) Single Wall Pipe
Installed under State Route 145, the 24” (600 mm) single wall corrugated pipe was the first use of HDPE by ODOT as a highway cross drain. The HDPE pipe replaced Nexon-coated corrugated steel pipe, which deteriorated after five years of use from the challenges of the mine water run-off.
The single wall pipe was able to hold up to the challenges of the area and survived a 500-year storm in 1997 when 15” (375 mm) of rain fell in 36 hours. The cover over the pipe ranged from 15”-18” (375-450 mm) and bankrun gravel was utilized as the cover.
The pipe was regularly inspected with little change to the pipe or pavement through 2007.
