The new Carquinez suspension bridge is the third bridge at this site and replaces the existing bridge, built in 1927. It carries traffic westbound on I-80.

The three-span 1,056-metre long structure was the first new major suspension bridge built in 35 years.

The bridge features two 125-metre high concrete towers, supported by 3.0 m diameter piles of 90 metres length and a 25-metre wide deck.

‘The bridge is designed to withstand quakes of 8.0 on the Richter scale.’
