Abstract

Mountain View, California, recently completed a $5 million project to join previously impassable portions of the Stevens Creek Trail and Wildlife Corridor. Beginning in October 1997, the city constructed four pedestrian bridges and upgraded a highway underpass to lengthen the nature trail. The largest of the bridges spans nearly 1,100 ft (335 m) and crosses two major roadways and two rail lines; it is one of the longest prefabricated bridges ever installed in the United States. The other three bridges, all less than 90 ft (27 m) long, span Stevens Creek and extend the trail at points where the terrain would otherwise be impassable. The project also included the widening of an undercrossing beneath support abutments of Highway 85, a feat that required excavation and installation of 300 ft (91 m) of tieback-anchored retaining walls.
