EnviroSlope Geogrid Wrap - Railway Trestle
LOCATION: Southern Ontario
SCOPE OF WORK: EnviroSlope Geogrid Wrap face slope to replace wooden railway trestle
PROJECT PARTNERS: Owner: St. Lawerence & Hudson Railway
This project used an EnviroSlope Geogrid Wrap face slope to replace a wooden railway trestle.
A railroad trestle bridge had reached its design life and needed serious repair or total replacement. Traditional methods of replacement would require the line to be de-commissioned for an unacceptable period of time. A solution had to be found to minimize this down time. A reinforced embankment was designed to encapsulate the existing bridge structure and minimize the down time from 6 months to 2 weeks. The design incorporated primary reinforcement layers at three foot lifts with the face wrapped with an erosion control blanket held in place with a bi-axial geogrid. The reinforced embankment also blended in well with the surrounding landscape and vegetation.
