Dr Salih made the call after touring affected communities on Saturday to ascertain the level of havoc after the rains destroyed farmlands and rendered some roads unpassable.
So far about six districts including Nandom, Lawra, Jirapa and Lambussie have all been cut off as a result the floods.
“I am heartbroken after our tour of the Upper West Region to ascertain the level of havoc on the roads as a result of the recent torrential rains,” Dr Salih posted on Facebook.
“The devastation of the roads is widespread and intensive, we, therefore, need massive and timely intervention to restore the roads. I have informed the Minister of Roads and Highways about the state of our roads and we expect swift intervention from his ministry.”
