Bollinger Canyon Road IHT Overcrossing

Construction continues on the Iron Horse Trail Bicycle and Pedestrian Overcrossing at Bollinger Canyon Road.

TRAFFIC ALERT: Night work (8 PM to 5 AM) is scheduled to take place on Wednesday, September 27^th through Friday, September 29^th. The night work will only impact westbound Bollinger Canyon Road from Alcosta Boulevard to BR1E, by reducing the lanes adjacent to the work to one lane.

Please use caution when traveling through the construction zone.

The purpose of the Iron Horse Trail Overcrossings Project is:

• To improve safety by eliminating conflicts between pedestrians/bicycles and vehicles;
• Improve vehicular traffic flow by removing the at-grade crossings;
• Eliminate unsafe crossing maneuvers by pedestrians and bicyclists,
• Encourages pedestrian and bicycle usage along the Iron Horse Trail; and
• Increase trail use by nearby schools by improving safety at the Bollinger Canyon Road and Crow Canyon Road crossings.
