In November 2021, Congress passed the Bipartisan Infrastructure Law (Infrastructure Investment and Jobs Act), a once-in-a-generation investment in the nation’s infrastructure. President Joe Biden’s administration proposed this legislation to rebuild America’s roads, bridges, and rails, expand access to clean drinking water, ensure every American has access to high-speed internet, tackle the climate crisis, advance environmental justice, and invest in communities that have too often been left behind.

Over two years have passed since Congress passed the Infrastructure Investment and Jobs Act (IIJA), and hundreds of substantial infrastructure improvement projects are already in full swing across the country. Highlighted below are a few of the top-funded projects underway in California, Hawaii, and western Nevada.

The Biden Administration invested $34.7 billion in public infrastructure and clean energy in California, including:

• $24.3 billion for transportation investments, including roads, bridges, public transit, ports, airports, electric vehicle charging stations, and electric buses.
• $3.7 billion in grants, rebates, and other incentives to boost the use of clean energy, buildings, and manufacturing. These funds are in addition to incentives created by the Inflation Reduction Act.
• $1.7 billion for climate resiliency and hardening against other threats.
• $2.4 billion for improving access to clean water and water infrastructure, including $278.8 million for replacing lead pipes and service lines.

Golden Gate Bridge Seismic Retrofit
IIJA Funding: $400 million
Construction Start Date: 2024
End Date: 2029

The Golden Gate Bridge in San Francisco will receive the final phase of a seismic retrofit, starting later this year. The first three phases were completed between 2002 and 2014. The suspension bridge carries about 40 million vehicles annually to and from San Francisco and communities to the north of the city.

The work on this upcoming $879 million phase will focus on the 6,450-foot-long main suspension span, the main towers, the south tower pier, and the fender. The Golden Gate Bridge, Highway and Transportation District expects the rest of the funds to come from state grants and district capital reserves. Crews will strengthen the foundations, install micropiles and rock bolts, build reinforced concrete shearwalls, and replace the housing roof and roadway deck with a precast concrete slab-on-steel stringer deck system. The additional hardening should make the structure more resilient to an earthquake or other disaster.

“The Golden Gate Bridge is an international icon and key transportation link for the Bay Area that serves tens of millions of residents and visitors every year,” said Denis Mulligan, District General Manager. “This vital funding allows us to finish strengthening the bridge against disasters. Thanks to [former] Speaker [Nancy] Pelosi, the Biden administration, and the entire Bay Area congressional delegation, the Golden Gate Bridge will be protected for generations to come.”

Dunsmuir GAP Project
IIJA Funding: $151.4 million
Construction Start Date: 2023

Work on the Dunsmuir GAP Project on Interstate 5 near Dunsmuir, from the Sacramento River Bridge to the Black Butte Overhead, will rehabilitate the pavement and restore the road to a state of good repair. The pavement has significant chain wear. Crews will replace existing concrete and asphalt pavement with concrete, construct rumble strips, replace signs, rehabilitate culverts, and upgrade guardrail, bridge railing, and traffic management solutions elements. This California Department of Transportation (Caltrans) project will provide an improved roadway for motorists and will require less maintenance over time.

A second contract in the same vicinity will replace the southbound bridge deck and railings on the Sacramento River Bridge on Interstate 5 in the City of Dunsmuir. The California Regional Water Quality Control Board has found elevated levels of chlorides on the deck, which suggests active corrosion. Caltrans plans to manage the replacement.

Otay Mesa East Port of Entry Project
IIJA Funding: $150 million
Construction Start Date: 2022
End Date: 2024

A joint venture between Caltrans and the San Diego Association of Governments, with support from state and federal partners, this $1.1 billion project will serve as a border crossing with Mexico to decrease wait times and fuel economic growth. It also aims to improve regional mobility, strengthen border security, and add resiliency. Current ports of entry are stretched to capacity, creating congestion and limiting economic growth. This will create a new and modern facility in the region.

This project aims to reduce wait times to 20 minutes, down from a current two to four hours. That will lead to fewer greenhouse gas emissions and will improve air quality. The project also aims to provide economic benefits by making freight traffic easier to cross the border. Additionally, the project will prioritize hiring local people from disadvantaged groups and establish a pre-apprenticeship program.

Numana Dam Fish Passage Project
IIJA Funding: $8.3 million
Construction Start Date: 2023

This project will support the recovery of Cui-ui and Lahontan cutthroat trout. These fish are culturally important to the Washoe Tribe of Nevada and California. The tribe’s ancestral lands surround Lake Tahoe. The Lahontan cutthroat trout have been listed as a threatened species. Overfishing and damage to their spawning area and greater numbers of nonnative fish have led to the trout’s demise. The project will open 65 miles of habitat along the Truckee River for the fish.

The project will install a permanent roughened rock ramp at Numana Dam, an irrigation diversion structure within the Pyramid Lake Paiute Tribe Reservation. The dam, installed in 1917, provides water to tribal farmers and ranchers. The project also will support Pyramid Lake’s recreational fishing.

“We are proud of our longstanding partnership with the Pyramid Lake Paiute Tribe and others to support recovery efforts for Cui-ui sucker and Lahontan cutthroat trout. Together, we have made significant progress over the last 50 years,” said Paul Souza, Pacific Southwest Regional Director for the U.S. Fish and Wildlife Service. “The investment of Bipartisan Infrastructure Law funds at Numana Dam will augment our past and existing recovery efforts for these iconic and culturally important fish by opening up more than 65 miles of historic habitat for the first time in over 100 years.”

Hydrogen Fueling Facility and New Buses
