In my Sunday column, a letter-writer suggested that one alternative to putting HOT lanes on Interstate 66 would be to double deck the highway, thus expanding its capacity. Readers responded with their own proposals for improving travel on one of the region’s most congested highways. While most travelers dismissed the idea of double decking as too expensive and way too ugly, many many do like the idea of expanding capacity by expanding the pavement.

Schwartz says he believes transit is the best way to solve congestion problems. Hamilton says carpooling and rapid bus service with limited stops along the Express Lanes would encourage transit. But Schwartz counters that similar promises about new rapid bus service were made regarding the 495 and 95 Express Lanes and neither actually happened.

Virginia officials have been saying for a long time that the traffic problems on I-66 are so bad that no single relief program will be sufficient. The toll revenue can raise money for other programs that could help get commuters out of their cars and open more highway space. Those efforts can include extra bus service and enhanced commuter lots.

He says it’ll induce more drivers to commute long-distance alone. He also says VDOT has made promises about providing robust bus service on the 495 and 95 express lanes but neither have come to fruition. “If they consider rapid bus service as a top justification for the project, then we expect guarantees that VDOT will fund rapid bus service in the corridor. They’ve failed to do it on the 495 and 95 Express Lane deals,” says Schwartz.

When new toll lanes open early next year along I-95 in Northern Virginia, stretching nearly 30 miles between the I-395 interchange and Stafford County, project leaders expect that one of the most successful HOV corridors in the country will continue to attract carpoolers to job centers inside the regional core.
