Stan Musial Veterans Memorial Bridge

Missouri and Illinois

Successful example

of

multi-state agency and stakeholder coordination

The third-longest cable-stayed span in the U.S., the new Stan Musial Veterans Memorial Bridge boasts a superstructure that employs steel-edge girder composite with the concrete deck and concrete delta-shaped pylons that rise 400 ft. above the river. HNTB served as lead designer for the Missouri and Illinois Departments of Transportation and completed design for the bridge within one year. The bridge features a 1,500-ft. main span that carries Interstate 70 across the Mississippi River in downtown St. Louis.

ACEC-Illinois Eminent Conceptor Award and ACEC-Missouri Grand Conceptor Award

The American Council of Engineering Companies of Arkansas awarded the bridge with its top honor, Grand Conceptor. It also named it first in the structural systems category.

Broadway Bridge over the Arkansas River

Arkansas

For nearly 100 years, the Broadway Bridge has been a critical traffic link between the communities of Little Rock and North Little Rock and a landmark dedicated to World War I veterans.

HNTB designed the main spans of the Broadway Bridge, which were composed of two 448-ft network tied-arch spans with steel plate girder approaches. The lengths of the five approach spans vary from 126-227 ft. The final design consists of inclined basket-handle arches with a framed-in floor system, which lowered costs. The tied arches allowed a signature structure to be constructed on the existing alignment ahead of the anticipated 180-day bridge closure by using an accelerated bridge construction technique to float the arches into place. The new bridge provides a safe and iconic mobility solution to the growing population.

Bob Kerrey Pedestrian Bridge

Nebraska

A signature structure and a point of pride, the bridge provides connection to two communities over the Missouri River

The HNTB steel structure has a graceful curvilinear S-shaped design that gently meanders from Omaha, Nebraska to Council Bluffs, Iowa, symbolizing the waters of the Missouri River that flows below. Despite crossing an area of the river that is only 800 feet wide, the bridge stretches out for more than 2,300 feet — making it one of the longest pedestrian bridges in the nation. The completed pedestrian bridge, along with an adjacent park and landing area, are the epicenter of activity. Visually striking and functional, the bridge is a catalyst for community involvement and economic growth.

National ACEC Grand Award; Design-Build Institute of America Design-Build Merit Award

The bridge provides connectivity to more than 150 miles of trails in Iowa and Nebraska has a park and landing area on the Omaha side of the bridge.

Tacoma Narrows Bridge

Washington

Proven engineering knowledge gave the Tacoma Narrows Bridge sure footing in the earthquake-prone area

HNTB was engaged to design a new structurally sound span by tapping into our expertise in seismic design. In analyzing ground motion studies and historical data from past area earthquakes, the team revealed that the large diameter drilled shaft foundation proposed for the structure was too high-risk to withstand the deep water, swift two way tidal flows and complex geotechnical features it would encounter.

Instead, HNTB proposed and, in just 10 days, delivered a conceptual design to use massive, deep-water gravity caissons to support the bridge. Firmly planted more than 200 feet below the water surface, the western caisson is 208 feet high — the equivalent of an underwater 24-story building. The eastern caisson is approximately 130 feet long, 80 feet wide and 234 feet high.

Tilikum Crossing

Oregon

The first long-span, cable-stayed transit bridge built in the U.S., honors the people who first lived in the Pacific Northwest region.

Tilikum Crossing, also known as Bridge of the People, is the only bridge of its kind in the U.S. It was the first transit-only, cable-stayed crossing that carries trains, buses, streetcars, cyclists and pedestrians. Operated by Tri-County Metropolitan Transportation District of Oregon, Portland’s public transportation service, also is the first bridge to be built across the Willamette River in the region in more than 40 years.

When it opened in Fall 2015, the Portland Milwaukie Light Rail Orange Line project was on time and under budget. Tilikum Crossing is the epitome of a project designed with community input. HNTB worked as the owner’s engineer on the design-build project, determining the bridge’s type, size, and conceptual design.

Honoring native residents of the region, TriMet named Portland’s 12th bridge “Tilikum Crossing.” “Tilikum” is drawn from the Chinook Wawa language that was used for centuries by Native Americans and newcomers to the area.

Tilikum means “people,” “tribe” and “relatives,” and symbolizes coming together. Over time, it also has come to mean “friends.”

Transit Bridge

Goethals Bridge Replacement Bridge

New York and New Jersey

A

dual cable-stay project and first public-private partnership in the northeast

A vital regional link, the Goethals Bridge carries I-278 over the Arthur Kill waterway, linking Elizabeth, New Jersey, NJ Route 439, Route I-278, the New Jersey Turnpike to the Staten Island Expressway. HNTB served as an extension of staff since 2004 supporting the Goethals Bridge Replacement Program. HNTB lead the initial concept development, cost estimating, preliminary design and constructability engineering for the Goethals project concurrent to the EIS Phase. HNTB became the Authority’s P3 technical advisor and full-time project management staff extension to provide technical, managerial and support services through this complex project’s procurement and design and construction phases.

Mario M. Cuomo Bridge

New York

First cable-stayed bridge across the Hudson River

The Mario M. Cuomo Bridge, an iconic twin-span cable-stayed crossing linking Westchester and Rockland counties in New York, opened to traffic on both spans in September 2018. The 3.1-mile bridge with its ancillary facilities is one of the largest projects in the United States and the biggest in the history of the New York State Thruway Authority.

Ben Franklin Bridge PATCO Track Rehabilitation

Pennsylvania and New Jersey

Delivered sooner than expected and under budget

As designer and construction monitor, HNTB helped the Delaware River Port Authority plan and execute three lengthy closures to accelerate the Ben Franklin Bridge Port Authority Transit Corporation Track Rehabilitation project. The 88-year-old bridge underwent a 3-mile commuter track replacement that required separate, continuous track outages, the longest in the line’s 50-year history. Two years after the project kicked off, the groundbreaking replacement project was completed sooner than expected with millions of dollars under budget and minimal disruption.

ASCE’s Outstanding Civil Engineering Achievement award

California

Delivering safety and security to one of America’s iconic landmarks

The 1.7-mile-long structure serves as a gateway for more than 40 million vehicles each year and is recognized by the American Society of Civil Engineers as one of seven engineering wonders of the United States.

Based in the San Francisco Bay region, the Golden Gate Bridge is in an earthquakeprone area. HNTB was engaged to work on completing a seismic retrofit for the Golden Gate Bridge, providing a range of construction services to the project. This included construction management, claims and schedule support services, inspections, and other related services. HNTB has also served as the designer of the new suicide deterrent system.

Mary Avenue Bridge

California

The first cable-stayed bridge, crossing an interstate highway in California

The Mary Avenue Footbridge connects suburban communities between two cities to schools and work centers previously divided by the highway. The bridge now includes gateway paths, extensive landscaping, and public art for viewing by bicyclist and pedestrians alike.

The 500-foot-long steel structure spans eight lanes of Interstate 280. Approximately 240 tons of steel were used for the project, which was built with a structural steel girder-and -beam superstructure. It is surrounded by nearly 12 acres of native landscaping, complete with sound wall reconstruction and 1,700 feet of lighted bicycle and pedestrian paths. HNTB served as lead designer and used value engineering methods to develop a visually stunning, functional and affordable project design.

Gerald Desmond Bridge

California

Improved traffic flow for Long Beach signature bridge

This project signifies three engineering and bridge design firsts for California:

• The first traffic cable-stayed bridge in California, the second cable-stayed bridge on the West Coast

• The first cable-stayed bridge in an active seismic zone

• The first segmental construction bridge in a seismic zone

HNTB, as part of a joint-venture team, provided technical oversight for the design/build contract of the 2,000-footlong cable-stayed Gerald Desmond Bridge for Caltrans and the Port of Long Beach. The Port of Long Beach wanted a bridge design that would provide an iconic identity for the entire Southern California area, similar to San Francisco’s Golden Gate Bridge. HNTB provided bridge type study, conceptual, preliminary and final design resulting in Long Beach’s vibrant, new structural icon.
