The Gerald Desmond Bridge’s Replacement Rises from the Waters

A bridge to replace the Gerald Desmond in Long Beach comes into being

The bridge has served its purpose. Half a century after it was built, the Gerald Desmond is still able to serve the City of Long Beach in southern California but it has come to be called “functionally obsolete” by engineers.

The stress caused by the higher number of cars and trucks that have come to use it as a result of the port’s growing importance to the U.S. economy has taken its toll on the massive structure. In fact, 15% of all imports that arrive to the country as cargo travels across the bridge, which connects the city with Terminal Island where several of the port’s large tenants are located.

Named after a former city attorney and councilman, it also has a water clearance that is too low for cargo ships, which have become much larger since 1968 when the bridge opened.

“The current bridge… is in dire need of replacement,” reads official website of the project to replace the bridge

After public authorities approved financing for the construction of a new bridge in 2010, work by a joint-venture involving Salini Impregilo began three years later.

By December of last year, workers reached a major milestone with the completion of the project’s two 515foottall (157 metre) towers for what will be California’s first cablestayed bridge for vehicular traffic.

“These new towers …are changing the Long Beach skyline,” said Long Beach Mayor Robert Garcia in a statement at the time. “The bridge is not only an important piece of infrastructure, its design will create a new iconic gateway into our city.”

As the main features of the new bridge, the towers will make it the secondtallest cablestayed bridge in the country once the $1.47billion project is completed at the end of 2019.

The next milestone to be reached is the construction of the 2,000-foot-long (610 metre) main span.

With 205 feet (62 metres) of clearance over the waters of the Back Channel — 50 feet (15 metres) higher than the existing span — the new bridge will be high enough to allow the latest cargo ships to pass underneath it.

With three lanes in each direction plus safety lanes, it will be wider and better able to handle the 68,000 vehicles that cross it every day. In a year, it is estimated that about 18 million trips will be made.

The bridge is an important artery in the U.S. trade system. It is designated as a National Highway System Intermodal Connector Route and part of the Federal Strategic Highway Network.

“This bridge will be a lifeline for California’s economy as 40 percent of the nation’s imports come through this complex,” said California Department of Transportation Director Malcolm Dougherty in the statement issued when the two towers were installed in December.

The new bridge is being build alongside the old one, which has remained open throughout the construction to keep traffic flowing.

When the new bridge is completed, the old one will be dismantled.

Demolition of the approaches to and from the old bridge has already begun. On July 4, several large excavators equipped with jackhammers and claws began tearing down an elevated ramp that connected eastbound Ocean Boulevard to the northbound 710 Freeway. The removal of the old connector ramp will enable the construction of a new one.

In Long Beach history, the Gerald Desmond Bridge is not the only structure to have stretched across the Back Channel. The first was a single railroad track built by Salt Lake Railway. By 1908, a bascule drawbridge replaced it. Around the time of World War II, the U.S. Navy installed a pontoon bridge, which served for decades until the erection of the Gerald Desmond. Opened in 1968, it has followed the economic and industrial development of Long Beach and the rest of the state until the huge volume of vehicular traffic the secondbusiest port in the U.S. required the construction of a new bridge.
