Roseville Tunnel is a 1,009-foot-long horseshoe shaped tunnel located near Roseville Road in the Roseville section of Byram Township, Sussex County, New Jersey. This Project is part of a larger project concerning restoration of passenger rail service on the Lackawanna Cut-off. NJ Transit selected the DB team of Schiavone/ McMillan Jacobs Associates to design and rehabilitate the Roseville Tunnel and include the following elements related to the tunnel and the tunnel approaches:

• minimizing water infiltration into the tunnel
• from the roof and /or side walls, developing
• structural repairs to provide a structurally
• sound tunnel, and maintaining clearances
• required for safe rail operations.

GM2 is part of the team providing services related to evaluating clearance requirements between new tunnel lining and track vertical alignment as well as the development of track typical sections. This team is working closely with the structural engineers to ensure the vehicle dynamic envelope will meet New Jersey Transit’s strict clearance requirements.
