Morning Poll: Pedestrian Bridge from Rosslyn to Georgetown?

If you try driving across Key Bridge at rush hour, you’re likely to encounter heavy traffic.

But drivers aren’t the only one dealing with congestion on the 91-year-old span that crosses the Potomac from Rosslyn to Georgetown. The bridge’s narrow pedestrian walkway is also typically jammed with walkers, runners and bikers, who sometimes come into conflict as they try to pass one another.

Pedestrians also impact traffic, as vehicles must wait for them to clear a crosswalk to take a ramp to the Whitehurst Freeway.

So what should be done to improve matters? Cross-river gondolas have been proposed, as have streetcars. But one self-described “transportation nerd,” writing on the county’s Mobility Lab website, has another suggestion: a dedicated pedestrian bridge.

Such a bridge could better accommodate all of those walkers, runners and bicyclists, while marginally improving vehicle traffic. Built parallel to the Key Bridge, one might expect the project to be similar in scope to the $12 million pedestrian span parallel to the Hot Metal Bridge in Pittsburgh, according to the writer, Sam Krassenstein.

What do you think about the idea?
