Project Profile:

John Weeks Footbridge

Project Summary

ISI donated the Gravelpave2 product to the Student chapter of the ASCE at Northeastern University. The students contacted Invisible Structures about controlling the erosion at Weeks Bridge. Rainwater flows off of the hard surface bridge and erodes the soil around the entrance (see top photo). Prior to contacting ISI, the students had investigated which solutions would be the best and discovered Gravelpave2 is what they were looking for. Gravelpave2 can control the erosion and provide a stable surface for pedestrians and wheelchairs.
