Opening elevated roadway marks major milestone in raising Bayonne Bridge

On Monday, February 20, 2017, our Skanska-Kiewit joint venture project team celebrated the opening of the new northbound roadway of the Bayonne Bridge. Connecting New York and New Jersey, the newly opened roadway sits 64 feet higher than the original and is nested within the upper reaches of one of the longest steel arch bridges in the world.

After demolition of the lower deck is completed this summer, the new bridge will allow for a total of 215 feet of clearance above the main shipping channel below. The extra clearance is essential in accommodating “New Panamax” ships, which are the latest and largest generation of container vessels named for the newly expanded Panama Canal.

The project is believed to be the first time a new roadway has been constructed above an existing bridge span that also remained fully operational, allowing for traffic to continue underneath. It is one of the most technical engineering challenges our team has ever undertaken, and we take great pride in the commitment and ingenuity of our team.

“Skanska is proud of the partnership we forged with Kiewit and the Port Authority of New York and New Jersey on the Bayonne Bridge ‘Raise the Roadway’ project, which will soon allow larger cargo ships to enter the ports in New Jersey and Staten Island while also improving the iconic bridge for the travelling public,” said Senior Vice President Keith Chouinard. “This is the most significant milestone yet for all of the people involved in this once-in-a-lifetime project—and a giant step towards the project’s completion.”

Each year, approximately 1.5 million vehicles cross the bridge between New York and New Jersey. The completed project will feature a complementary southbound roadway and will provide drivers with a safer and more enjoyable crossing that includes 12-foot lanes, shoulders, a median divider and a 12-foot bike and pedestrian walkway. It also will offer the possibility of future mass transit options.

The Bayonne Bridge originally opened to the public in 1932. At that time, the now-famous Sydney Harbour Bridge was under construction in Australia. Closely replicating the design of the Bayonne Bridge, it measures just 25 inches shorter. To this day, the trusses of these sister bridges are considered two of the world’s most elegant arches, made of a sleek, high-strength alloy steel.

Watch a time-lapse video from November 2016 here.

The total length of the new bridge will be 7,159.5 ft. The main span remains 1,675 ft.

Our team removed all 152 steel cables supporting the old roadway and replaced them with shorter cables to support the new span.

The gantry crane constructs one rope-supported section of the new roadway at a time.

In 1931, the Bayonne Bridge was the longest steel arch bridge in the world when it opened. Currently, the Bayonne Bridge is the fifth longest steel arch bridge in the world.

Construction on the southbound approach expected to begin after the demolition of existing roadway in 2017.

This week, celebrate the infrastructure on which we all depend

May 12-16 is Infrastructure Week, celebrating the emerging solutions, innovative approaches and best practices in modernizing our nation’s infrastructure, on which the U.S. economy depends. Infrastructure is at the core of what Skanska does,  with projects ranging from public-private partnerships like Elizabeth River Tunnels in Hampton Roads, Va., to transit projects like the Expo Line Phase 2 in Los Angeles. Here’s a look at some of the key numbers associated with these and other infrastructure projects completed or underway by Skanska and our partners:

3CAT210G -Aerial-6 March 2011

The Catskill/Delaware Ultraviolet Light Disinfection Facility uses 56 massive UV units to neutralize waterborne pathogens in New York City’s drinking water supply.

2 billion gallons: Amount of water that can be treated daily at the Catskill/Delaware Ultraviolet Light Disinfection Facility in Mount Pleasant, N.Y. The facility, which was completed last year, is the largest of its kind in the world.

1.5 miles: Length of the 7 Line subway extension in New York City, between Times Square and the rapidly growing Hudson Yards section.

46 minutes: Time it will take to travel between Los Angeles and Santa Monica – even during rush hour – on the Expo Line Phase 2 light rail. When the full line opens, estimated ridership is expected to reach 64,000 daily riders by 2030.

14,600 tons: Amount of blacktop needed to repair 14 miles of Colorado’s Highway 7 after a 1,000-year flood destroyed portions of it in September 2013. Our team repaired the stretch of highway over six-and-a-half weeks, with crews working 12 to 14 hours a day, seven days a week to finish the road ahead of schedule.

442 feet: Length of the tunnel boring machine – nicknamed Lady Bird – that our team is using to bore a 13-mile tunnel 100 feet under Washington, D.C., to hold sewage awaiting processing at the Blue Plains Advanced Wastewater Treatment Plant.

21 miles: Length of the stretch of Interstate 4  in Orlando, Fla., for which the I-4 Mobility Partners team  – of which Skanska is a part – has been selected to design, build, finance, operate and maintain improvements through a P3 agreement. This P3 approach will enable the Florida Department of Transportation to deliver these essential highway improvements – including reconstruction of 15 major interchanges and replacement of more than 75 bridges – 20 years sooner.

What’s it like building a New York City subway?

In some ways, Skanska’s work expanding New York City’s labyrinth of subways is like most of our other heavy civil assignments across the nation: blasting rock, moving earth and pouring concrete are common tasks everywhere, as is ensuring the unimpeded and safe passage of pedestrians and traffic.

But in other ways, working beneath the Big Apple’s streets is an undertaking found few other places. You might not see daylight for your entire shift, and your mobile phone likely won’t have service. Roaming in this different world are tunnel-boring machines, which use their heft – up to five stories tall and stretching the length of a football field – to carve subway tubes out of hard Manhattan schist. And as everything going to and coming from an underground site is transported through an access shaft, the crane atop that shaft becomes your lifeline.

Here are what some Skanska team members had to say about the experience:

“It’s like building a ship in a bottle.”

– Nick Vitucci, superintendent

“This is a different kind of job. Here, you have to create the area in which you work.”

– Mike Ceglio, safety engineer

“I’ve been on really long concrete pours from maybe 4 a.m. to 9 p.m. Afterward, we’d surface and there might be a foot of snow on the ground – it had fallen when we were underground and we hadn’t expected it. Those are always interesting experiences.”

– Michael DeMonaco, field engineer

“Down here, everyone has each other’s back. You spend more time with your family down here than with your family at home. Everyone on our team is a really good person – salt of the earth.”

– John Kiernan, superintendent

In this video, our teams used their smartphones to capture one another describing what it’s like working on these projects.

Many roles in current subway expansions

Skanska’s roles in both of New York City’s major subway expansion projects cover all aspects of new subway construction, from the gritty tasks involved with shaping the rock to the detailed craftsmanship associated with installing the escalators, wall panels and signs that will be part of New Yorkers’ commutes for generations to come.

In our work bringing the Second Avenue Subway line to Manhattan’s dense Upper East Side, a joint venture of Skanska/Traylor is mining and concreting a cavern at 86th Street for a new subway station. This builds on previous work that a joint venture of Skanska/Shea/Schiavone performed in boring two 22-foot-diameter tunnels between 63rd and 92nd streets for the trains to roll.

On Manhattan’s Far West Side, a joint venture of Skanska/Railworks is installing architectural finishes and mechanical, signal and other systems in new tunnels and a new station to extend the No. 7 line to the city’s rapidly growing Hudson Yards section. Again, this adds to yet another joint venture that Skanska participated in (Shea/Schiavone/Skanska) in boring the tunnels – which extend 1.5 miles from the Times Square station – and building the structure of the new station.

Outgoing Mayor Bloomberg takes first ride on New York’s No. 7 line

Skanska is building the 1.5-mile extension of New York City’s No. 7 subway line. It won’t be completed until next summer. But a special guest still got to ride those rails on December 20: outgoing Mayor Michael Bloomberg, who visited this Skanska joint venture project as the final stop on his farewell tour of the city.

Mayor Bloomberg 7 Train

During his 12 years as mayor, Bloomberg – who steps down December 31 – championed development of Manhattan’s far West Side, which the expanded No. 7 line will serve. So, with the track work and other basic infrastructure mostly in place, it was possible to give the mayor the honor of this ride. He boarded a special dignitary train at the current No. 7 line terminus at Times Square, and took it to the new station our team built, at 34th Street and Eleventh Avenue, by the Javits Convention Center. This is the first subway extension financed by the city in more than 60 years.

Bloomberg said all workers involved in expanding this subway should be proud.

“The Skanska team is extremely proud of the work that has been completed on the 7 Line and is honored that Mayor Bloomberg ended his farewell tour to the city at one of our projects,” said Paul Olson, Skanska project manager. “We look forward to completing this challenging project in the upcoming year and bringing subway service to the West Side of Manhattan .”

Our team at work on the No. 7 line extension.

Skanska joint ventures have been involved in both phases of this work: first boring the subway tunnels, and currently installing the systems and finishes. A joint venture known as S3II – consisting of Shea, Schiavone and Skanska – began construction in December 2007. Our team’s $1.1 billion contract included mining about 12,000 feet of 22-foot diameter tunnels, using two tunnel-boring machines named after Bloomberg’s daughters, Emma and Georgina. That work was completed in June 2012. They also constructed the cavern for the new underground station.

Since August 2011, another Skanska JV – this time with Railworks – has been working under a $513 million contract to fit out the new station with walls and architectural finishes; lace the tunnels and station with a myriad of wires and pipes for utilities and communications systems; place the tracks; and outfit four major ventilation facilities with all mechanical, electrical and communications systems.
