$14 million Mini Mousehole project in Truckee wraps up

TRUCKEE, Calif. — The town of Truckee and Caltrans last week gathered for a ribbon-cutting ceremony to mark completion of the $14 million Highway 89 Undercrossing Improvement Project, nicknamed the “Mini-Mousehole.”

The tunnel structure provides a pedestrian/bicycle path through the Union Pacific railroad embankment just southeast of downtown Truckee.

Because the railroad is in continuous use, the project used a unique “road header” machine to excavate the tunnel as the concrete tunnel structure was inserted into the hole dug into the railroad embankment.

Over 900 cubic yards of soil and rock was removed. Portal walls, pathway paving and a Truckee Tahoe Regional Transit shelter completed the project.

The construction of the pedestrian/bicycle tunnel will not only provide a safer route for pedestrians and bicyclists along the heavily traveled Highway 89 between Truckee and Tahoe City, it will encourage non-vehicle, multi-modal forms of transportation benefiting the Tahoe Basin-Truckee environment.
