The proposed freeway's path west of San Antonio Valley Road would have bypassed Mount Hamilton either to the north toward State Route 237 or to the south toward San Jose's Evergreen district. The feasibility of the project came into question, however, as constructing a freeway over the Diablo Range near three of its highest peaks (Mount Hamilton included) would have been very difficult. The project also faced stiff opposition from taxpayers, environmentalists, residents of the area looking to preserve their area's local charm, and the Lick Observatory (A freeway through the mountains near the observatory would render it useless by light pollution). The freeway plan was quietly abandoned after Congressman Pombo failed in his reelection bid in 2006.
