CITY HALL — Not only is an underground extension of the Long Beach (710) Freeway feasible, but it could take the form of a tunnel connecting to the Glendale (2) Freeway near the Eagle Rock-Glendale border, according to a draft report commissioned by state transportation officials.
The California Department of Transportation recently released the draft report on the results of its roughly $6-million “710 Tunnel Technical Study,” which evaluated fault lines, soil composition and groundwater to determine the feasibility of building an underground tunnel. The study found that tunneling is feasible in all five route zones, which could include extensions to the 2 and Foothill (210) freeways.
State officials stressed the study was “route neutral” and paid equal attention to all route zones, which encompassed Alhambra, Glendale, La Cañada Flintridge, Los Angeles, Monterey Park, San Marino, South Pasadena and Pasadena.
