Arlington County is planning to award contracts this year that will result in two new ways to get into the busy Pentagon City Metro station.

In September, the county is expected to award a design/build contract for a new elevator that will run directly into the station from the southwestern corner of S. Hayes Street and 12th Street, near the Pentagon City mall.

The elevator will complement an existing elevator on the southeast corner of the intersection.

About 95 percent of the $5 million project will be funded with state and federal funds. The county is hoping that the elevator will be open by Nov. 2014.

Also this year, the county is hoping to award a contract to refurbish and reopen an abandoned pedestrian tunnel that connects the northeast corner of the Hayes/12th intersection to the Metro station’s mezzanine.

The county is hoping to finalize the design of the refurbished tunnel — the design process has been on-going for nearly a decade — and to put the project out for bid by the end of the year.

The tunnel could reopen by the winter of 2014.

Arlington County Transportation Director Dennis Leach suggested that the project has been made more complicated thanks to the tunnel’s proximity to the headquarters of the Transportation Security Administration and the Drug Enforcement Administration.

“We’re still working through a few remaining design issues and we have to conclude some property-related negotiations,” he said. “It is a very complicated small project. That tunnel was built as part of a site plan development. We have to work with the adjacent property owner and the adjacent tenants.”

With nearly 35,000 combined entries and exits on an average weekday, the Pentagon City Metro station is the second-busiest Metro station in Arlington — second only to Rosslyn.
