Highway Bridge Inspection and Repairs
How to Shrink Inspection Time of a Three-Mile Bustling New York Highway Bridge from 2 Months to 3 Days
What was the challenge?
The Governor Mario M. Cuomo Bridge is a spectacular 3.1-mile, cable-stayed, twin-span bridge built in 2017 and opened to traffic in 2018. Its angled towers soar to about 280 feet and support 192 stay cables made of more than 4,900 miles of steel strands. In compliance with Federal Highway Administration regulations, this bridge must be inspected once every two years for cable and fixture integrity and painting maintenance. The client, a government contractor conducting bridge inspections, hired Alpha Platforms’ operated rental service to inspect this bridge, looking to save on the budget.
- The challenge was that the daily commuter traffic hovered around 150,000 with peaks of 170,000 vehicles per day. One of four critical commuter bridges crossing the Connecticut river, this bridge supports the New York Thruway, a critical artery around New York City.
- Previously, the bridge inspection had been completed from a motorized scaffolding basket hanging on stay cables. The inspectors had to move the cage every 20 feet and climb up and down the cables to ascertain their integrity. At the rate of one drop per day on average, such a project would have taken 1-2 months.
- Typically, high winds would endlessly delay completion of the inspection: basket swaying is dangerous, creating unsafe working conditions for the bridge inspectors. Since the Mario Cuomo Bridge spans the Connecticut River tunnel and high riverbanks, windy days are a frequent occurrence.
What was the solution?
What was the outcome?
How could the client have reduced a 1-to-2 month-long inspection to just 3 days? Alpha Platforms’ custom-designed telescopic boom trucks are sturdy and reliable, reaching up to 300 feet high with up to a 135-foot side reach. The 230 boom lift, in this case, with its 115-foot side reach, parked on each side of the bridge only 3 times: enough to cover the entire length of its cabled portion, significantly reducing work duration and downtime.
Thanks to the swiveling jib cage and the boom’s extreme stability–even with 36-50 mph gusts --the platform operator continuously moved the basket, offering unparalleled flexibility and access speed to thoroughly inspect the cables and towers. Inspectors discovered a broken cable sleeve and requested the A-230 for one more day to fix it.

It was a pleasure to work with Alpha Platforms, the crew was skilled and helpful, the equipment was top-notch. Our installers appreciated the security of the platform vs working off of a swing stage, it made their job easier and more efficient. From the first meeting thru to the end of the work day everything ran as smoothly as it could. We will definitely be partnering with Alpha Platforms on future projects. Thank you for your help!
I had an emergency project on a 140' high voltage tower and needed Alpha Platforms next day. They were so helpful and expedient walking me through the entire process so I was comfortable with the deal. They showed up to my site next day and cut about 2 days off of the project due to the safety, speed and efficiency of their lift and operators. I'll never rent or hire another lift company. I would recommend Alpha platforms for all your high reach needs.

That is a fine piece of equipment! And the competent, professional group that goes along with it is just the cherry on top. I really appreciate everything. I'm sure we'll be able to use Alpha again in the future as we get these opportunities. In fact, it will only help our business knowing we have a safe, reliable solution to these over 50‘ height challenges.
We had an exceptional experience with Alpha! They are professionals, great operator team. Overall reliable, recommended will certainly return for my future needs hands down.
My company used alpha lifts to clean a 14 floor building and they were great. Very accommodating, always on time, and will work with you to get the job done safe and sound. The lifts they provide are state of the art and can pretty much reach any low rise building under 250 feet. I’d recommend them to anyone doing window cleaning or facade cleaning, or anything king of height access work!
We wanted to give it a try and see what this boom truck could do. We loved the idea of a wide basket that could reach up to 30 feet and get to the brick wall over the roof. The main reason we loved the truck was how it maneuvered the boom to lower the bricks inside a dumpster, which was located behind the truck. It saved us at least one extra day of work. It all went great.
Alpha has the most efficient and leanest site setup time I’ve ever seen. My brother, who is the top climber of our group, first struggled to understand how this cage could go around the tower better than the crane - and when it did the whole 360°, he became a believer. Also, each laborer said how incredibly safe they felt - very different from the small crane basket. We were able to secure and push back the panels in place without the basket ever moving.
The project was performed successfully, and we were really glad to have contactless means of reaching the building, as we all know that pipe scaffold might damage the structure, in this case, very very sensitive.
