Northwest Bridge Avenue on the east side of the St. Johns Bridge will remain closed until late March or early April 2022 for emergency repairs addressing rockfall problems.
The road has been closed since January 5 by rockfalls and ODOT crews have been evaluating the slope above the road. Early January rains aggravated conditions, making the hillside too unstable to re-open the road to traffic.
ODOT geotechnical engineers have been evaluating repair options and determined that the best solution is a pinned mesh system, which will stabilize the slope and minimize the potential for additional rockfall events on the road. The process involves drilling bolts into the hillside, which will hold the robust steel mesh in place on the hillside.
In preparation for the work, crews will remove vegetation from the slope and perform rock scaling to take down loose, unstable rock from the hillside.
