The Purple Line’s impact on Wayne Avenue might be worth another look, transportation experts with the county’s planning department suggested Monday.
In a report to the planning board, the experts recommended studying the impact of a street-level Purple Line on Wayne Avenue, versus one worming beneath it. Total ridership along the Bethesda-to New Carrollton route could increase by 2,100 with that tunnel, and without blowing the mass-transit project’s shot at scoring federal funds, the experts estimated.
That finding flipped the script on a report from the state transit administration, which didn’t dig deeper into the Wayne Avenue tunnel idea, and didn’t make an “apples to apples” comparison between tunneling and running the ride at street level, the experts claimed.
The state’s report proposed two flavors of transportation — bus rapid transit and light rail, each with three levels of investment (low, medium and high). None of those rides rolled beneath Wayne Avenue.
Despite the transportation experts’ holler for a street-versus-tunnel study, they still think a street-level ride is the way to go. Rolling on Wayne could skirt issues of a tunnel portal west of Sligo Creek. It also would keep a station at the planned library on Fenton and Bonifant Streets in Fenton Village, which could use the economic boost, the experts wrote.
If future Purple Line studies make a mess of the street-level route or downtown Silver Spring traffic, results of the proposed tunnel study could be an ace up the transit administration’s sleeve, the experts said. So what if the tunnel adds $175 million to the project, they argued.
The experts also showed some love for street-level routes through the downtown Silver Spring area. That’s because tunneling beneath the central business district would rule out a station at the planned library. However, the experts felt the Purple Line’s impact on Bonifant Street parking, as well as access to the Whole Foods Market parking lot on Wayne near Fenton, should be re-evaluated.
All but one of the state’s proposed routes through the central business district roll at street level between Georgia Avenue and Fenton Street. Only high-investment light rail rolls beneath the library, and doesn’t offer a stop there.
