Plan ahead: #NewYorkRoad tunnel closure for essential maintenance from 12 February. #NewYorkRoadTunnel, located just outside the #LeedsCityCentre and on Leeds #InnerRingRoad, will close to all vehicles on Monday 12 February until the autumn to enable essential maintenance of the #NewYorkRoadFlyover. #LeedsCityCouncil along with construction partner #BalfourBeatty will carry out repair works and replace 27 bearings on #NewYorkRoadFlyover. Bearing replacement on the flyover is a vital process, that whilst only completed generally every 25-50 years, is essential to ensure the serviceable life of the flyover is maintained and subsequently this section of the flyover can remain open in the long term. Modern bridges are designed to make future bearing replacement straight forward. However older bridges, such as the #NewYorkRoadFlyover, require substantial temporary works with heavy equipment including temporary foundations to support the bridge at each bearing. To maintain the structural integrity of the bridge the work needs to be phased and some structural components strengthened https://lnkd.in/ewp3VRuY #LeedsNews #LeedsStar #LeedsStarNewspaper #LeedsCityCouncil #VisitLeeds #LeedsCity #Leeds

Temporary bridges are a versatile solution, whether you're looking to improve traffic flow on and off an active site, provide pedestrians with access whilst existing infrastructure is closed, or reconnect a flooded community. However, there are a number of considerations to be made when looking to install a temporary bridge: ✅ Access onto site ✅ Available space ✅ Working with the right partner Find out what else in our article below. #engineering #construction #bridges #temporaryworks

Bridge Replacement in Hackney: A Timely Reminder for Infrastructure Inspection 🏗️ A 150-year-old bridge has finally been replaced after being in very poor condition, and a full replacement is needed to avoid an unplanned closure. This is where Pole Star can come into action! 🏗️ Regular inspections of a bridge help identify potential hazards such as cracks, corrosion, or structural weaknesses that could lead to accidents or collapses. You can achieve this with our Structure Examination System (SES). We have designed this solution to improve the inspection process by providing thorough and precise evaluations of structural strength. 🔧 The technology provides detailed reports and actionable insights, helping engineers and maintenance teams to make informed decisions.

Gordie Howe International Bridge The Gordie Howe International Bridge project will connect the U.S. and Canada with what one of the developers behind it says will be the longest cable-stayed bridge in North America. Construction of the bridge deck began in December 2022, with work advancing from both sides of the Detroit River. Over the past few months, the two sections have been steadily approaching each other. By the end of May, all of the concrete slabs on both the Canadian and U.S. sides were in place, leaving just an 11-meter gap to complete the 2.5-kilometer-long bridge deck. 2). $1.3 Billion Movable Bridge, Connecticut Development will be getting underway for a new, movable, $1.3 billion bridge in Connecticut following the awarding of construction contracts by Amtrak. Amtrak says the new bridge will enhance reliability and reduce delays for its intercity services, the Connecticut Shore Line East commuter line, and freight operators along the Northeast Corridor (NEC), the busiest rail corridor in the United States. 3). I-55 Bridge Replacement Connecting Tennessee and Arkansas Tennessee Governor Bill Lee recently announced an $800 million project to replace the aging Interstate 55 bridge that connects Tennessee and Arkansas. 4). Washington-Oregon Bridge The Oregon Department of Transportation is set to receive $1.4 billion for the Interstate Bridge Replacement Program, which aims to replace the two aging vertical lift bridges that carry I-5 over the Columbia River, connecting Portland, Oregon, and Vancouver, Washington. The Federal Highway Administration (FHA) says the new bridges will be modern, seismically resilient and multimodal, offering safe and accessible options for driving, walking, biking, rolling and riding transit. 5). Sagamore Bridge Replacement Project, Massachusetts The Massachusetts Department of Transportation is set to receive $993 million for the Sagamore Bridge Replacement Project in Cape Cod, Massachusetts.

The windy, two kilometre stretch of SH1 over the 430 metre-high Brynderwyn Hills north of Kaiwaka has been plagued by slips since the highway was first constructed. Several accidents have occurred over the years, the worst being when a bus lost control due to brake failure on a steep section of the highway, causing it to crash and killing 15 passengers. In more recent times several severe weather events have closed the highway for periods due to reoccurring slips. Cyclone Gabrielle caused massive damage with 18 slips along the length of the two kilometre carriageway of SH1, causing it to be closed to all traffic for periods of time. Consideration is now being given to constructing a new alignment because of its importance as the main corridor to Northland. With the expectation that it will time to plan and construct, a decision was made to reinstate the existing highway in the short term and make it less vulnerable to weather events. After consultation with the affected communities and local authorities, and following geotechnical investigation and design work by consultancy WSP in New Zealand, enabling work began in October last year. Fulton Hogan was appointed as lead contractor supported by Goodman Contractors Limited which provided the earthworks, while Geovert undertook the stabilisation work. Some 20 other contractors were also and, while the main rehabilitation work was carried out, the highway was closed to traffic for a period of almost four months. There were 27, 30 and 40 tonne Moxys on site, together with D6 and D8 bulldozers, a number of 30-40 tonne excavators, several piling rigs, and a local helicopter company was contracted to airlift diesel fuel to the site. The biggest challenge for contractors was working in the comparatively narrow and hilly site, the instability of the ground and the propensity of heavy rainfall. A 24/7 online monitoring system was put in place, with a number of strategically placed sensors sending data to onsite engineers via their mobile smartphones. Once earthworks, cuttings and stabilisation were completed parts of the highway were reinstated with aggregate sub-base foundations and resurfaced with AS20 asphalt. Lane marking and construction of safety guardrails followed and an additional asphalt surface layer will be laid in spring, once the ambient temperature gets warmer. The highway had been scheduled to reopen in mid-May. But due to another large slip in April, on what is known as Kauri Corner, additional geotechnical investigation was required along with the removal of a further 60,000 cubic metres of soil and debris and batter strengthening work. Overall and by contractors working seven days a week, some 115,000 hours has been spent onsite re-establishing the highway, which reopened to two-way traffic on June 28 at a cost of $84 million funded through the Crown Recovery Fund.
