Work begins on I-66 project inside the beltway

ARLINGTON, Va. (AP) -- Work is underway on a project officials say will make Interstate 66 inside the Capital Beltway the nation's first roadway with dynamic tolling on all lanes during peak traffic times.

Officials broke ground Monday on the project expected to be complete next year. Toll prices on the roadway will be adjusted based on volume to help keep traffic moving at highway speeds.

The project includes the installation of tolling equipment and signs on nearby local streets.

Toll revenues will fund improvements that give commuters other travel options, including new and enhanced bus service and bike-share programs. The Commonwealth Transportation Board also recently approved a nearly $10 million program to fund such projects.

A 4-mile segment of eastbound I-66 will also be widened from the Dulles Connector Road.
