As Arlington County prepares to build a new pedestrian and bike bridge in Shirlington — two decades in the making — some continue to express concerns about safety.

Late last week, the county brought advanced concept designs to the community for a new pedestrian and bike span between the Shirlington and Green Valley neighborhoods, and for maintenance to the existing bridge, which has only a narrow pedestrian sidewalk.

While incorporating previous public feedback into the design, questions still cropped up about safety and convenience, particularly regarding the crosswalks across busy S. Arlington Mill Drive and Shirlington Road, which provide access to the W&OD and Four Mile Run trails. Both are heavily-traveled by cyclists.

The first part of the project will be to improve and update the existing bridge. The bridge is in need of routine maintenance and resurfacing, and this project provides a chance for other needed renovations, the county says.

Based on public feedback, staff said they will widen the sidewalk to about 7 feet from a previous 3-5 feet. They will also coordinate the design aesthetic with the renovations to Jennie Dean Park, while adding new guardrails.

However, despite some urging it, the county won’t be removing the slip lane from the I-395 ramp. While admitting that it’s not bike or pedestrian-friendly, county officials say there isn’t much that can be done at present.

The lane is owned and maintained by the Virginia Department of Transportation. Adding a crosswalk there would also increase risk for an incident due to traffic taking the right turn with speed, while the lane it could lead to traffic backing-up on the I-395 ramp.

“We, at the county, are very much interested in [removing the lane],” said Jason Widstrom, Arlington County Transportation Capital Program Manager. “Unfortunately… it is not within our authority to remove it.”

Construction for these renovations should begin in the late summer or early fall of this year and be completed prior to the end of the year.

Then, at the end of 2021 or beginning of 2022, construction will begin on a prefabricated, 15-foot pedestrian and bike bridge located 20 feet to the west of the existing bridge. It will parallel the existing bridge, will be multi-use, and have “enhanced pedestrian treatments.”

Additionally, improvements are being made to those crosswalks at Arlington Mill Drive and near the Four Mile Run Trail.

Based on feedback, the county is widening pedestrian ramps and the refuge median, redesigning curbs and the crossing to allow for better sightlines, and adding new rapid flashing beacons to improve visibility of the crosswalk. There’s also thought of trimming trees to further help sightlines.

Crosswalk safety, particularly near the Four Mile Trail, has long been a concern for residents.

“County staff is well aware of the history of the crosswalk and the troubles of trying to cross at this location,” says Widstrom.

Funding for these projects are coming from a state grant and will cost just over $1 million.

County officials said they would like to do a longer term study about adding a bridge that goes over Shirlington Road and thus separates vehicle and pedestrian traffic.

That study remains “down the road,” however, and costs to add that bridge could exceed $8 million.

In the meantime, said Widstrom, “we are trying to make the situation a bit better.”
