Study says the proposal would not be cost-effective

A Maryland Transit Authority study recommended against building a tunnel beneath Wayne Avenue between the Silver Spring Transit Center and Mansfield Road in Silver Spring as part of the Purple Line, claiming the tunnel is not cost-effective.
The MTA and Gov. Martin O'Malley (D) are considering three options for a 16-mile mass transit route that would connect downtown Bethesda to New Carrollton via Silver Spring.
All three options would include a tunnel east of Manchester Road under Plymouth Street, emerging on Arliss Street. The high-investment option also would include a tunnel from the Silver Spring Transit Center that would emerge at Wayne Avenue east of Cedar Street.
The MTA studied a tunnel option that would extend the tunnel beneath Wayne and downtown Silver Spring to Mansfield Road. A short, street-level rail line on Wayne would then connect to the tunnel near Manchester.
