The Longest Subterranean Highway In The U.S.

"Bill Vardoulis of Corona del Mar freely admits he suffers from an acute case of tunnel vision. For three years, the 64-year-old mechanical engineer, former Irvine mayor and transportation wonk has exhausted his spare time on a crusade to build the longest subterranean highway in the United States.On paper, the $3.5-billion tunnel complex -- with room for trains, trucks, cars and utilities -- runs for about 10 miles under the rugged Cleveland National Forest. The tollway would provide a second major link between Orange and Riverside counties, two fast-growing neighbors struggling to improve the chronically congested freeway that connects them."
