Major Roadworks Set to Disrupt Drivers Across Regions

The Simister Island junction will be fully closed on the weekends of Sept. 26 and Oct. 10 so contractor Costain can remove overhead gantries.
National Highways selected the Simister Island closure dates to avoid major regional events, including sporting fixtures, concerts and Manchester Pride; the October timing was adjusted around a Pussycat Dolls concert.
The Grimsby A180 scheme is expected to be completed by early November, after the resurfacing phase and the subsequent installation of new central-reservation barriers.
During the Arizona SR 260 blasting closures, flaggers and law-enforcement officers will direct traffic and the speed limit will be reduced to 25 mph between Walters Lane and the Gila County Yard.
The Arizona blasting schedule may change because of weather or other unforeseen circumstances, and additional intermittent closures are expected after Oct. 6.
Major road construction projects across the UK and Arizona will disrupt traffic through the end of 2030, with three distinct sites facing closures and speed restrictions. Manchester's busy Simister Island junction—used by 90,000 vehicles daily—will close completely on two September and October weekends for overhead work. Meanwhile, Grimsby drivers face a two-week contraflow on the A180, and Arizona motorists will encounter hour-long delays during rock blasting operations on State Route 260.
The Simister Island interchange linking the M60, M62, and M66 motorways will undergo extensive construction lasting until 2030, including new lanes and widened roads. National Highways has scheduled full junction closures for the weekends of September 26 and October 10 so contractor Costain can remove overhead gantries. National Highways timed the closures carefully—avoiding Manchester Pride, concerts, and sporting events. October's closure was shifted to sidestep a Pussycat Dolls concert scheduled for an earlier date.
Traffic speeds will drop and reduced lane availability will remain in place throughout the multi-year project. Drivers should expect significant delays during peak travel times, with the biggest impacts coming during the planned closure weekends.
The A180 in Grimsby will shift to a contraflow arrangement starting with an overnight closure on September 20. This setup supports resurfacing work and replacement of the central-reservation barrier. National Highways expects the contraflow to remain in place for up to two weeks, with completion targeted for early November.
Once resurfacing finishes, crews will install new central-reservation barriers before reopening the road fully. Drivers should plan for slower speeds and congestion during this period and consider alternate routes if possible.
State Route 260 near Star Valley in Arizona will close intermittently on September 22, September 29, and October 6 during rock blasting as part of a $76 million widening project. Flaggers and law-enforcement officers will direct traffic, and the speed limit will drop to 25 mph between Walters Lane and the Gila County Yard. Drivers should expect delays lasting up to one hour during each blasting window.
Arizona transportation officials warned that the blasting closure schedule could shift due to weather or other unforeseen circumstances. Additional intermittent closures are expected after October 6 as the widening work continues. Motorists should monitor local traffic updates before traveling through the affected area.
