    Description

    The purpose of this project is to provide a new access point to the Red Line northwest of the Charles River that will accommodate equipment, labor, and material delivery into the tunnel more efficiently. The MBTA Red Line subway northwest of the Charles River consists of a below grade tunnel with access for equipment, such as Hi-Rail vehicles, and maintenance only available just east of the Kendall/MIT station, some four miles from Alewife Station at the First Street gate. With the existing tunnel being over 25-ft below ground surface near Alewife, a tunnel is the most practical means of providing access from grade to the tunnel below for access.
