1) Project Name: Newburgh-Beacon Bridge Re-Decking Project
Project Location: Newburgh and Beacon, New York
Notes: The video will include:
• MPT configuration
• Deck Removal
• Stress Relief Joint Removal
• Steel Repairs
* Installation of new steel grid deck panels
The first new steel grid deck panels were just delivered last week. They will begin being installed next week so that they can be part of the video.
Abstract: The New York State Bridge Authority (NYSBA) operates and maintains six vehicular and one pedestrian span over the Hudson River in New York. Our Newburgh-Beacon Bridge consists of twin spans each nearly 7,800’ long carrying traffic on I-84. Each span is an articulated deck truss with a thru truss over the river channel.
The north span re-decking project, the largest in NYSBA history at $101.8M, includes the full replacement of the original light-weight concrete deck with a new partially-filled, steel-grid deck, poured in place, removal of stringer stress relief joints and steel repairs to increase the load rating of the bridge. The southern half of the deck has been completely removed. Installation of the new grid panels is expected to begin in April. The contractor expects to complete the project by September 2022, which is nine months ahead of schedule. NYSBA has contracted with Yonkers Construction Co. for the re-decking project, with engineering and inspection oversight by HDR, Inc.
Background: The original Newburgh-Beacon Bridge (the north span) was opened to traffic on November 2, 1963 as a two-lane bridge (one eastbound; one westbound). Due to capacity issues, the south span bridge was constructed with four lanes and opened on November 1, 1980. The north span was closed to be widened, and it re-opened in 1984. I-84 has three eastbound lanes on the south span and three westbound lanes on the north span.
Operations on our video:
• MPT configuration
• Deck Removal
• Stress Relief Joint Removal
• Steel Repairs

2) Project Name: Grist Mill Bridge, Hampden, Maine – The first FRP Composite Tub Girder Bridge Superstructure in the U.S.
Project Location: Hampden, Maine
Notes: A professional videographer was on site to capture the installation of this innovative bridge superstructure, and we intend to professionally produce a 20–30-minute virtual tour to showcase the technology in a visually compelling and interesting manner. An example of a recent 5-minute documentary production using footage from this project and one other in Washington State can be viewed on YouTube at the following link: https://youtu.be/etQQdo2Gdew
Abstract: The first commercial installation of AIT Bridges’ fiber-reinforced polymer (FRP) composite tub girder superstructure in place of traditional construction materials marks a significant milestone in the use of sustainable, cost-competitive bridge solutions that will last 100+ years.
The Maine Department of Transportation sought to replace a bridge that felt more like three bridges after decades of repairs and additions, with one that requires little-to-no maintenance over its life. Part of a two-year, two-mile road reconstruction project, Grist Mill Bridge construction started in Spring 2020 with the demolition of the old bridge and reopened to traffic at the end of 2020; however, due to cold weather conditions, final paving and site restoration continues, and the project is still active as of April 2021.
The five composite girders span 75’, and because the composite girders are lightweight, the contractor was able to pre-assemble modules, consisting of two girders with all utilities and attachments, and lift them into place with fewer crane picks. This would not have been possible with traditional materials without a much larger crane.
During its load test on January 31, 2021, four dump trucks weighing approximately 260,000lbs combined were parked in the center of the bridge (as shown in the attached overhead drone image). Test results showed a total deflection of ½”.
The girders were developed by the University of Maine’s Advanced Structures and Composites Center, and are engineered and manufactured by AIT Bridges in Brewer, Maine.
3) Project Name: Benjamin Franklin Bridge Rehabilitation of Suspension Spans and Anchorages
Project Location: Philadelphia, Pennsylvania; Camden, New Jersey
Notes: Video creation by AECOM with contributions from the Delaware River Port Authority, Greenman Pederson Inc, and Skanska. Upon completion this video will be reviewed and approved by the DRPA and Department of Homeland Security.
Abstract: The Delaware River Port Authority (DRPA) is a regional transportation agency that serves as steward of four bridges that cross the Delaware River between Pennsylvania and New Jersey: the Ben Franklin, Walt Whitman, Commodore Barry and Betsy Ross Bridges. Through its Port Authority Transit Corporation (PATCO), the DRPA also operates a transit line between Camden County, New Jersey and Center City Philadelphia.
The Benjamin Franklin Bridge Rehabilitation of Suspension Spans and Anchorages project consists of five separate design projects combined together into one construction project. The combination of projects improves the construction coordination among work locations and improved construction access which shortens durations, improves work processes and reduces impacts to PATCO service by allowing multiple work locations during track outages.
The majority of the work to be completed consists of repairs to various steel components on the suspended spans, maintenance painting and installing a dehumidification system for the main cables and anchorages.
The work also includes repairs to reinforced concrete and steel members and painting inside the anchorages, rehabilitation of the North and South Walkways; replacing decorative lighting; and widening of the North Walkway in Camden.
The steel repairs include replacement of the critical components of the suspension system including pin and link assemblies at both the main towers and anchorages using temporary bracing and jacking. The steel repairs also include replacement of the wind lock assemblies and repairs to the lateral bracing.
Project cost: $216.9 Million
Construction phase: 2020-2024
Scheduled completion: Winter 2024
4) Project Name: Gordie Howe International Bridge project
Project Location: Windsor, Ontario, Canada/Detroit, Michigan, USA

US Project Flyover April 2021 – https://youtu.be/aqbBYCWyCCM
Canadian Project Flyover March 2021 – https://youtu.be/QYVvKpqYFp0
Abstract: The $5.7 billion (CDN) Gordie Howe International Bridge between Windsor, Ontario and Detroit, Michigan, is being delivered through a public-private partnership (P3). Windsor-Detroit Bridge Authority (WDBA), a Canadian Crown corporation, is responsible for oversight of the construction and the operation of the new crossing.
The project has four components: Canadian and US Ports of Entry (POE), the bridge itself and the Michigan Interchange.
The 53 hectare/130 acre Canadian Port of Entry and the 68 hectare/167 acre US Port of Entry will include border inspection facilities for commercial and passenger vehicles as well as for pedestrian and cyclists. Once completed, they will be amongst the largest inspection plazas in North America.
The bridge will include six-lane (three lanes in each direction) for commercial and passenger vehicles as well as a multi-use path for pedestrians and cyclists. With a clear span of 853 metres/0.53 miles, it will have the longest main span of any cable-stayed bridge in North America.
The Michigan Interchange consists of the primary connecting ramps to and from the US POE as well as local road improvements including four new road bridges, five new pedestrian bridges as well as a reconfiguration of I-75 interchange ramps and service drives
Construction of the Gordie Howe International Bridge project started in 2018. Once complete, it will not only deliver much-needed transportation improvements for international travellers, it will also provide jobs and opportunities for growth to the Windsor-Detroit region and beyond.
5) Project Name: Union Pacific – Thebes Bridge
Project Location: Illmo, MO and Thebes, II
Abstract: Vector Construction Inc. was contracted in 2020 by Union Pacific to complete structural concrete repairs on the Thebes Bridge over the Mississippi River. The rehabilitation project was initiated in 2018 to address concrete deterioration and cracking on the substructure that has occurred over the life of the bridge.
The bridge is a five span cantilever truss bridge that was constructed in 1905 to span the Mississippi River between Illmo, MO and Thebes, Il. The Thebes bridge is listed as a historic bridge structure and is one of the earliest surviving cantilever truss bridges in the United States. It was designed by legendary bridge engineer Ralph Modjeski and the substructure was built with a combination of concrete and limestone blocks.
The 116 year old bridge is in fairly good condition but is showing signs of deterioration. A long-life cycle, freeze thaw and a series of floods have caused cracking and concrete delaminations to the substructure. The Mississippi River has caused major flooding in the area with 4 historic floods since 1993 creating an unstable work environment for rehabilitation. Roads were constructed prior to repair work to enable access to the bridge.
Repairs on the concrete substructure include large scale concrete removal and replacement on the arches, stitching large cracks in the arch, ballast repair (pin back to structure), crack injections and miscellaneous shotcrete repairs of delaminated concrete. The project commenced in the spring of 2021 and is anticipated to take one year to complete.
6) Project Name: GLX Green Line Extension, Light Rail Viaduct
Project Location: Cambridge/Somerville Massachusetts
Abstract: The GLX Green Line Extension is a $1.0bn light rail project that is currently in construction just north of the City of Boston. The project is Design-Build, and is scheduled to be complete by early 2022. The Client is the Massachusetts Bay Transportation Authority. The Contractor is a joint venture of Fluor/Middlesex/Balfour Beatty/Herzog. STV is Lead Designer. The viaduct structure is a major element of the work, and supports over one mile of light rail track. The viaduct has over 40 spans, with several laid out on sharp radii.
The Viaducts accommodates a split in the Green Line to provide service on a separate branch line. This split occurs directly over active commuter/freight rail tracks (known as Grand Junction). In the Eastbound direction, the diverging light rail track wraps under the main viaduct while itself still supported on viaduct structure.
The first 1,000 feet of the proposed Viaduct require demolition of an existing viaduct, which supports active track. Rapid construction is required to minimize service disruption.
The proposed Lechmere Station is being built within the footprint of the Viaduct, and has an elevated center platform. Support for the station and the center platform are being incorporated into the Viaduct.
The work is being done in a congested area with traffic and public disturbance constraints.
7) Project Name: Southern Beltway
Project Location: Canonsburg, PA
Abstract: This video tour of the Southern Beltway project will provide aerial coverage of the new construction of a 13 mile long limited access tollway in Western Pennsylvania. The footage will show five major construction sections that are nearly complete with four lanes of new concrete paving, as well as one construction section that is still in the works with ongoing earthwork, paving and bridge construction. The new highway includes four new interchanges, two cashless tolling facilities, and over 20 bridges.
The video will provide a narrative overview of the work that has been performed and will give specific information about many of the bridges throughout the project. Bridges that will be covered include: steel plate girders (curved and straight), pre-stressed concrete I-beams, pre-stressed concrete box beams, and existing bridge widenings.
The Southern Beltway project has been under construction since 2014 with an early action project and it will open to traffic this coming October with final completion in 2023. The project includes over 25 million cubic yards of earthwork, 40 miles of pipe, 168 football fields of pavement, and 2.5 miles worth of pre-stressed beams.
