Regarding Sharon Brady's Jan. 16 letter "Blocked Access," there are other escape routes from Mount Washington than McArdle Roadway, including Sycamore Street (known as the Burma Road), Greenleaf Street or the Wabash Tunnel.
Why not use one of these? Southern Avenue, Boggs Avenue or Woodruff Street down to Route 51 and then either to the Liberty Tunnels or the West End Bridge to the North Shore.
Generations of our family have lived in our home on the Mount for over 100 years and never needed the Wabash Tunnel for a safer route off.
No need to reinvent the tunnel; simply reply on a plain, old-fashioned Pittsburgh map.
