During its first decade, the bridge carried fewer than 40,000 vehicles per day. By the start of the 21st century, the old Tappan Zee Bridge was "decaying" and "overburdened". The deteriorating structure bore an average of 140,000 vehicles per day, substantially more traffic than its designed capacity. The collapse of Minnesota's I-35W Mississippi River bridge in 2007 raised worries about

Approximately 70 percent of the sediments targeted for dredging were removed (totaling more than 1,900,000 cubic yards (1,500,000 m ) of sediment). On July 19, 2016, a crane used for the construction of the bridge collapsed onto the existing older bridge. Five people were injured, including three drivers and two bridge workers; no one
8424-530: The environmental impacts. However, when the instability of the eastern span was discovered in September 2018, it was decided to destroy it outright. The explosive demolition of the eastern approach took place on January 15, 2019, while the western approach was lowered onto a barge on May 12, 2019, and hauled away. Reports of a coverup of structural problems emerged in December 2018. Dozens of bolts holding
8541-402: The field, called "bowl seating", potentially raising the 49ers franchise value up as much as $ 250 million and offering at least $ 300 million in advertising and concession deals, the majority of which from paid corporate naming. The architectural design would be reminiscent of San Francisco buildings. The project planning did not get off to a good start, however, with contention between
8658-656: The first stadium that will have both a green roof and solar panels. The 49ers are exploring collaborative opportunities with the Environmental Protection Agency to explore environmentally friendly components including: Levi's Stadium received a Gold LEED ( Leadership in Energy and Environmental Design ) Certificate.

8775-400: The game, making re-sale very difficult. In addition, older 49ers fans say that people are more segmented at Levi's Stadium in comparison to Candlestick Park, leaving tailgaters with large expanses of empty parking stalls and a more desolate tailgating experience. Pilots flying into San Jose International Airport have frequently complained of being blinded or disoriented by the lights from
8892-416: The green roof to an organically maintained rooftop farm . The vision for this quarter-acre—named the Faithful Farm after the 49ers' loyal following—came from team CEO Jed York and his wife. Danielle York, a former science teacher, was particularly interested in a dedicated space that could help the building achieve some of its goals for sustainability. Lara Hermanson and Matt Sandoval of Farmscape worked with
9009-403: The home to their new stadium. San Francisco voters in 1997 approved $ 100 million in city spending to build a new stadium and an attached shopping mall at Candlestick Point . However, even after voter approval to grant economic help for the project, the stadium was not constructed. This was because owner Eddie DeBartolo Jr. was facing legal troubles, which led him to surrender ownership of
9126-407: The light towers and scoreboards. The stadium is directly in the flight path of one of the airport's runways. According to Bay Area NBC affiliate KNTV in 2016, there had been at least 43 complaints about the lights since the stadium opened. Levi's Stadium has also received heavy criticism for the way fans are treated on hot days during early-season afternoon games. The majority of fans are seated on
9243-649: The likelihood of the Raiders sharing Levi's Stadium with the 49ers. In January 2016, after losing their bid to relocate to Los Angeles to the Los Angeles Rams , the Raiders withdrew their request to move to Los Angeles, and joint tenancy at Levi's again surfaced in general discussion.

9594-437: The new bridge's bus lanes finished in 2020, leaving one bus lane in each direction. Early plans also called for Metro-North Railroad commuter rail service on the bridge, but ultimately the span was built without commuter rail tracks. During construction, the project's website referred to the crossing as the "New NY Bridge." However, other sources referred to it as the "New Tappan Zee Bridge". Governor Andrew Cuomo signed
9711-478: The old bridge started in November 2017 with the removal of the first steel section from the Rockland County approach. The work continued to April 2018 including the removal of the truss sections. In May 2018, the 10-million-pound main span was removed, leaving only the east and west approaches. The original plan was to complete the remaining demolition by taking down spans piece by piece in order to minimize
9828-450: The old bridge. An opening ceremony for the south span was held on September 7, 2018, and traffic started using the new span three days later. The bridge's official name, which does not include the words "Tappan Zee" like its predecessor, has been controversial since its announcement. A petition and several legislative bills have sought to officially rename the bridge to the Tappan Zee Bridge or similar names. The Tappan Zee river crossing
9945-682: The option of riding VTA light rail (Valley Transportation Authority) to the stadium. The closest light rail station is the Great America station, which is located just west of the stadium in the median of Tasman Drive.

10296-467: The roads that link the stadium to the freeway. Moreover, with residents in the low-income housing by 2016, traffic would be permanently increased, further damaging the already-limited methods of transportation to the park.

A presentation by a whistleblower included allegations that the bolts had broken due to hydrogen embrittlement , which weakened the metal. The number of failed bolts was abnormally high for a project the size of this bridge. Engineering experts warned that
11817-513: The structural problems could compound, causing the girders to fall and the bridge to collapse. The issue was known as early as February 2016, when New York state officials had begun testing some bolts for breaks.

12285-417: The wake of Davis' death, the possibility of the 49ers and Raiders sharing the stadium became a stronger possibility. However, by October 2011, the 49ers were far enough along on the stadium to have reportedly already sold over a quarter of the luxury suites , meaning the Raiders would be forced to be secondary tenants. In October 2012, Oakland Raiders owner Mark Davis told reporters he had no plans to share
12402-484: The year. The lighting system reportedly has the ability to be synced to music, although it has yet to be demonstrated.
