Mechanically stabilized earth walls, or MSE walls, are commonly used to stabilize backfill around bridges or for retaining walls along freeways. In the last 15 years, UDOTs use of MSE walls has become routine where retaining walls are required. UDOT has a database of over 700 MSE walls in use across the state-owned transportation system. The walls are "a valuable asset," said Chief Geotechnical Engineer Keith Brown. "We need to maintain walls the best way we can."
