As the train rumbles its way across the 115-year-old Alhambra trestle in Martinez, loud creaks and rattles can be heard. And unlike more modern bridges, dozens of its bolts and bridge supports are rusted.
The trestle was originally built in 1899 and reinforced in 1929. The railroad replaced the rail deck in 2003, but the trestle’s support structures are 85 and to 115 years old.
