PHOENIX — To deter unsafe lane changes that can result in crashes, Arizona Department of Transportation crews installed a series of lane separator posts by this weekend along the westbound US 60 (Superstition Freeway) HOV lane between Kyrene Road and Interstate 10 in Tempe.

The white polyurethane posts, also known as lane delineators, are being installed to discourage westbound US 60 drivers using the HOV lane from making sudden lane changes as they approach the I-10 interchange.

Sudden lane changes from the westbound HOV lane have contributed to crashes along this section of US 60 in recent years. While most have been minor, non-injury crashes, some have been serious. The crashes can cause significant delays for drivers on the westbound Superstition Freeway.
