Mead Way has been put under a 24-hour road closure whilst the works are carried out. This includes the footway and cycleway between the Meads roundabout and the Westmead Drive junction.
To get around the closure on a bike, you will need to divert through Westlea, following the Route 45 signs, as shown on the map below. There is also a public footpath in the vicinity whereby you can push your bike, but with the recent weather, this is very muddy between Great western Way and Westmead Drive.
