Work is due to start on Monday on a major road resurfacing scheme in Keady town centre.
Costing in the region of £270,000, work has been earmarked at Kinelowen Street, Davis Street, Bridge Street, Victoria Street and Market Street.
And to minimise disruption, the work – which will require road closures – is due to take place at night.
Roads are due to be strengthened and resurfaced and, along with ancillary work, the Department for Infrastructure says it will improve road safety and deliver significant benefits to road users.
The road closures will be in operation Monday to Friday, from 8pm until 7am, between Monday, July 23 and Saturday, August 11.
Diversions will be clearly signposted and local access maintained.
A Department spokesperson said: “Some delays can be expected however and additional time should be allowed when planning any journeys.
“The planned dates are subject to favourable weather conditions and the Department will keep the public informed of any change.”
