Fairfax County voters approved a bond issue yesterday that will allow the county to borrow $135 million to finance 14 road projects, including two segments of the cross-county Springfield Bypass.

With all but 1 percent of the vote counted, the bond issue -- the largest in Virginia's history to be approved by any locality to finance roads -- won by 72 percent to 28 percent of the votes cast.

"It shows that the people of the county understand the problem," said Fairfax County Board Chairman John F. Herrity, a leading proponent of the road bond. "This is one step in solving the problem. It's certainly not a panacea."

Herrity called the margin of passage of the bond "an overwhelming victory" that he said would help to hasten the construction projects.

Of the $135 million, about $90 million will pay for two segments of the bypass, a road that planners say will roughly parallel the Capital Beltway, eventually connecting Rte. 1 in the south with Rte. 7 in the north.

The two segments will connect the Dulles Access Road with Rte. 50 in western Fairfax, and Rolling Road with Beulah Street in southeastern Fairfax.

An additional $13.2 million will go to construct a new road connecting Lockheed Boulevard and South Van Dorn Street in the Rte. 1 area of Fairfax, just south of the Beltway.

Most of the other projects involve widening existing roads, adding turning lanes and improving badly congested intersections.
