Geotechnical drilling was set to begin yesterday on the 710 Tunnel Technical Study in the L.A. area. Currently the 710 freeway ends along the city of Los Angeles-Alhambra boundary but was intended to run north to a junction with the 210 and 134 in Pasadena. The tunnel technical study will assess the feasibility of building a tunnel to complete the segment. Caltrans and CH2M HILL will be performing the borings which will go up to 250-ft deep. Seismic lines will be performed as a part of the study as well. Source: LA Times.
