A55, A494 and A483 Annual Essential Cyclic Maintenance works between 3rd of May - 3rd of November

Where and Why?

Work to carry out essential cyclic maintenance works to the A55, A494 and A483 dual carriageways.

Works will include grass cutting / weed treatment / litter collection / drainage cleansing / sweeping / structural maintenance and inspections / highway and vehicle restraint systems inspections.

Routine maintenance and inspection work on highway infrastructure is vital for the safety of road users and includes a wide range of activities such as, for example, gully emptying and their inspection to identify significant defects, which reduces the risk of flooding on our motorways and trunk roads.

Diversions and Safety Measures

The work will be carried out between 3rd May and 3rd November with works currently programmed from 18:00 nightly and will include main carriageway lane closures and full slip road closures.
