El Porvenir Vehicular Culvert Bridge Rehabilitation 2011
The culvert bridge rehabilitation will allow cars and trucks to keep using the crossing. Vehicles are used to transport produce, agriculture workers and health clinic personnel across the river. Closing the bridge due to significant deck and approach damages, as has been done in the past, would be a huge blow to the people of El Porvenir, Tula, and Guayabo. Without the bridge, farmers struggle to bring their crops to market and the villages are cut off from vital resources. DEID had a few major components of the rehabilitation including a new reinforced concrete slab, gabions, and an upstream debris catcher. The reinforced concrete slab was attached to the old surface using epoxy and “L”-shaped rebar. The gabions, large and strategically placed cages of rocks, provided downstream scour protection, thus preventing further erosion at the abutments of the bridge. The debris catcher was implemented to keep trees and other large items from crashing down stream during the storm and blocking the culverts. The project was successfully completed in July 2011.
