MU-605 Road Closure Gate Passes Two MASH Crash Tests

In rural areas across the country, farm-style gates have long been used to close highway access ramps during inclement weather. However, these gates often required road crews to manually operate them while standing directly in the path of traffic—a dangerous task, especially during low-visibility or high-risk conditions.  These farm-style gates may also create a high risk of damage to the vehicle and injury to its occupants.

Recognizing the serious safety concerns, many State Departments of Transportation (DOTs) have since reevaluated this approach. The result? A growing shift toward safer, more efficient roadside solutions.

Enter the MU-605 Manual Road Closure Gate—a game-changing alternative designed to be safely operated from the side of the roadway. Mounted to existing luminaire poles, this gate removes the need for operators to stand in active lanes, reducing exposure and improving overall safety. Best of all, the MU-605 is entirely manual and doesn’t require a gate operator system to function.

One DOT, which has relied on the MU-605 for over three decades as part of its National Highway System, recently conducted another series of crash tests to re-evaluate the gate’s impact performance.  The first set of crash tests was successfully conducted in the mid-1990’s.  In June and July of 2025, the MU-605 successfully passed (2) additional tests in accordance with MASH 3-61 Safety Criteria, confirming its ability to minimize risks to drivers in the event of a collision.
