McKenzie Over-Length Detection System

State Route 242 crosses the Cascade Range at McKenzie Pass. This mountainous highway is difficult for longer vehicles to navigate because of its tight curves and narrow lane widths. ODOT completed installing OLDS, McKenzie Over-Length Detection System, and it is used to automatically measure the length of vehicles and provide warnings to drivers. These vehicles could then turn around before reaching the pass, avoiding potential crashes and associated delays.
