Long Beach International Gateway

The Long Beach International Gateway, originally known as the Gerald DesmondBridge Replacement, is a cable-stayed bridge that carries six lanes of Interstate 710 and a bicycle/pedestrian path in Long Beach, California, west across the Back Channel to Terminal Island. The bridge replaced the Gerald Desmond Bridge, which was completed in 1968 and named after Gerald Desmond, a prominent civic leader and a former city attorney for the City of Long Beach.

Contents

The 1968 steel arch bridge developed numerous issues, and the Port of Long Beach decided it would be best, from an economical perspective, that the bridge be replaced. After several years of studies, a cable-stayed bridge with 205 feet (62 m) of vertical clearance to be built north of the existing bridge was identified as the preferred alternative in the final environmental impact report (2010 FEIR). [1]

The new bridge allows access to the port for the tallest container ships after the older bridge is demolished. It is the first long-span cable-stayed bridge in California and the first and only cable-stayed bridge in the Los Angeles metropolitan area. [2] For the bridge to be so tall, long approaches were required to allow trucks to cross. [3] A joint venture of Parsons Transportation Group and HNTB performed preliminary engineering for the main span and the approaches. Earlier reports had studied and discarded various alternatives, including an alternative alignment with a new bridge south of the existing bridge, rehabilitation of the existing bridge, and a tunnel instead of an elevated bridge. [1]

Design

The 1968 roadway was four lanes (two in each direction) with a fifth climbing lane on each end. The replacement bridge carries a six-lane roadway with emergency lanes on each side, and the grade has been decreased by building a longer approach, despite the higher vertical clearance over the Back Channel; the planned improvements brought the bridge up to current freeway standards. [4] The replacement bridge also carries the Mark Bixby Memorial Bicycle-Pedestrian Path and observation decks over the water along the south side of the bridge. The path is named for Mark Bixby, a longtime proponent of adding bike lanes to the new Gerald Desmond Bridge replacement [5] [6] and a descendant of one of the original founders of Long Beach. Mark Bixby died in a March 2011 plane crash at the Long Beach Airport. [7]

The 1968 bridge was designated as a portion of Ocean Boulevard and was therefore operated by the City of Long Beach. When it opened to traffic on October 5, 2020, the replacement bridge was redesignated as the western (southern) extension of I-710 (extending its terminus to its intersection with State Route 47) and is now the responsibility of Caltrans, District 7. [4]

From west to east, the new bridge spans a total of 8,800 feet (2,700 m), consisting of: [8]

By extending the approach structures, approach grades are reduced to no more than 5 percent. [1]

As the tallest structure in the area, the 2020 cable-stayed bridge is a prominent addition to the Long Beach skyline. [9]

The replacement bridge was unanimously approved by the City of Long Beach in late September 2010. [10] A project launch meeting was held at the Port of Long Beach on November 22, 2010, attended by Long Beach Mayor Bob Foster, U.S. Representatives Dana Rohrabacher and Laura Richardson, Senator Alan Lowenthal and Caltrans Director Cindy McKim. [4]

Caltrans, Port of Long Beach, and Metro officials reviewed seven potential engineering and construction firms, selecting four as qualified final lead bidders: [11]

Three of the pre-qualified bidders submitted proposals by March 2012, with Kiewit dropping out at the bid stage. [12] In May 2012, the Long Beach Board of Harbor Commissioners approved Port of Long Beach staff’s recommendation that the “best value” design-build proposal to replace the Gerald Desmond Bridge was submitted by the SFI joint venture team, comprising Shimmick Construction Company Inc., FCC Construction S.A. and Impregilo S.p.A., [13] and the contract was awarded to the SFI JV in July 2012. [14] Major participants in the joint venture also include Arup North America Ltd. and Biggs Cardosa Associates Inc. [15]

The project has been completed as a design-build in contrast to the traditional design-bid-build used typically in infrastructure improvement. [15]

During the groundbreaking ceremony on January 8, 2013, two helicopters hovered 515 feet (157 m) above ground level, illustrating the height of the two cable towers for the planned replacement bridge. [16]

The project was originally estimated to cost $800 million in 2008. [17] By 2010, costs had increased to $1.1 billion, [10] and funding identified in 2010 for the replacement bridge included $500 million contributed by Caltrans, $300 million contributed by the USDOT, $114 million from the Port of Long Beach, and $28 million from Metro. [4] As of 2016, the current project estimate is $1.5 billion. [2]

Construction issues

The new bridge was delayed shortly after breaking ground. The new piers were delayed by the relocation and/or removal of numerous old and active oil wells and utility lines, which prevented foundation work from beginning. The bridge is located in the midst of the Wilmington Oil Field, one of the most prolific oil-producing fields located in the United States. [18]

Another part of the cost increase and schedule delay is attributed to a 2013 redesign of the support towers. [19] Caltrans and the Port of Long Beach required the tower redesign, executed by the SFI joint venture, allegedly to ensure seismic safety and to preserve long term structural integrity. The redesign set the estimated completion of the bridge back by 12 to 18 months. [20] Other cost increases are attributed to extra oversight required by innovative, yet contractually compliant products and materials proposed by the designers of the replacement bridge. [2]

The roadway for the approach structures was supported during construction by an underlane self-launched movable scaffolding system (MSS), [21] and is the first project in California to use a MSS. [22] The MSS was designed to bridge the 235 ft (72 m) span between piers and to support the concrete as it was poured for each span. Once the concrete had cured, the MSS moved to the next pier and repeated the pour. The orange MSS was used on the western (Terminal Island) approach, and a similar blue MSS was used on the eastern approach. [22]

Construction progress

By October 2014, work had started on the pilings which would serve as foundations for the new bridge's piers. [23] The two cable-stay support towers were started in March (eastern tower) and April 2015 (western tower). [21] Approach spans were underway by April 2016. [22] By August 2016, the project had passed the halfway mark, and the two cable support towers were already more than 200 ft (61 m) high. [24] On December 5, 2017, a "topping-out" ceremony was held to celebrate the completion of the two cable support towers. [25] A virtual opening ceremony was held on October 2, 2020. Motor vehicle traffic opened in both directions on October 5, 2020, [26] although the bicycle/pedestrian path remains incomplete as of August 2024. [27]

Naming

For the first eight months after its opening, the bridge was called the Gerald Desmond Bridge Replacement. Mayor Robert Garcia and Assemblymember Patrick O'Donnell coordinated a community effort to decide if a new name was warranted. Family of Gerald Desmond and native Long Beach residents with former mayors Beverly O'Neill and Bob Foster favored keeping the original name; Foster felt a change would be disrespectful to the namesake of the original bridge, civic leader Gerald Desmond. [28]

In May 2021, Senator Lena Gonzalez and Assemblyman O'Donnell announced that the name "Long Beach International Gateway" had been chosen through a public survey [29]

<span class="mw-page-title-main">Cable-stayed bridge</span> Type of bridge with cables directly from towers to deck

A cable-stayed bridge has one or more towers, from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly.

The eastern span replacement of the San Francisco–Oakland Bay Bridge was a construction project to replace a seismically unsound portion of the Bay Bridge with a new self-anchored suspension bridge (SAS) and a pair of viaducts. The bridge is in the U.S. state of California and crosses the San Francisco Bay between Yerba Buena Island and Oakland. The span replacement took place between 2002 and 2013, and is the most expensive public works project in California history, with a final price tag of $6.5 billion, a 2,500% increase from the original estimate of $250 million, which was an initial estimate for a seismic retrofit of the span, not the full span replacement ultimately completed. Originally scheduled to open in 2007, several problems delayed the opening until September 2, 2013. With a width of 258.33 ft (78.74 m), comprising 10 general-purpose lanes, it is the world's widest bridge according to Guinness World Records.

An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons deviating upward from the deck. In this concept, they remain part of the main bridge superstructure.
