The following were among actions taken by the Fairfax County Board of Supervisors at its Jan. 11 meeting. For more information, call 246-3151.

ROAD BOND:The supervisors voted to begin plans for a $150 million road bond referendum this spring to help pay for the Springfield Bypass and other highway projects.

At the first meeting of the new board, elected last November, supervisors voted to hold a public hearing Feb. 8 on a bond referendum that could be held as soon as April 12.

Supervisors did not specify exactly what projects the bonds would pay for, but officials said part of the money might speed construction on two sections of the Springfield Bypass, between Rte. 50 and West Ox Road in the northwest part of the county and between Beulah Street and Rolling Road in the southeast.

The bond referendum was a major plank in the election platform of newly-elected board Chairwoman Audrey Moore.

In a related matter, the board voted to create a 10-member Transportation Advisory Commission to examine other ways of paying for roads, such as increased sales and property taxes.

The board also authorized using money from old road bonds already approved by voters to buy land in the path of new road projects, such as other sections of the Springfield Bypass. County Executive J. Hamilton Lambert noted in a memo that this measure "entails some risk" because if voters defeat the new bond issues and the new projects are not built, the land will have been bought needlessly. But he said buying the land early will speed projects and reduce costs.

TRANPORTATION OFFICE:State Transportation Commissioner Ray Pethtel announced that the Department of Transportation will send mechanics, equipment operators, engineers and a "Springfield Bypass Czar" to its Northern Virginia office to oversee work on the bypass and HOV-lane extension on I-95. Last year, former board Chairman John Herrity and other supervisors criticized the state transportation department for not providing full services at its Northern Virginia office.

TRANSPORTATION SURVEY:The board heard the results of an April driver survey that found that more than 70 percent of the county's 337,000 workers drive to work alone. The survey also found that almost half the county's workers drive half an hour or more to work, and that 44.2 percent of workers living in Fairfax County also work there.

DUCK HUNTING:Responding to complaints from Mount Vernon District residents that duck hunters shooting along the Potomac River endanger boaters, hikers and residents, the board asked the Legislature to ban waterfowl hunting along the Virginia shore of the Potomac between Alexandria and Prince William County.
