Commuters between Londonderry and Belfast are being "massively inconvenienced" by three sets of major roadworks, DUP MP Gregory Campbell said.
He criticised the DoE for failing to liaise properly with residnets in the Drumahoe area, several of whom have complained.
A DoE spokeswoman said that while Drumahoe was on schedule to finish by September, other works on the road would not be completed until 2009.
Mr Campbell said that more joined-up thinking would have greatly reduced the delays being experienced by motorists.
He said: "These roads not only cater for numerous motorists on a daily basis, but also for thousands of people commuting by bus between the cities.
"There are roadworks at Drumahoe which cause substantial tailbacks, further motorway work at the Randalstown end of the M2 for over two miles with carriageway width reduced, and then yet more work on the M2 at Sandyknowes on the final approach to Belfast, causing yet more delays.
"Everyone accepts the need for these works and the inevitable disruption they bring while work is ongoing, but to have three major pieces of work going on at the same time on the main road between the capital city and the Maiden City in Northern Ireland does leave the department open to the charge that insufficient liaison took place at the planning stage."
Mr Campbell said the DoE's Roads Service now needed to urgently review the operation of these schemes in order to try and ensure as smooth a flow of traffic as possible.
A DoE spokeswoman said the Roads Service was "fully aware" of the potential disruption to traffic arising from the ongoing major improvement works on the Westlink, M1 and M2 routes.
She said: "Extensive traffic management measures, aimed at reducing congestion, have been implemented along these routes in partnership with the police, Translink and the freight transport industry.
"To minimise road works disruption overall across Northern Ireland, Roads Service is making every effort to complete as many schemes as possible during the summer months, when there is generally less traffic. Members of the public are kept informed of roadworks, delays and alternative routes on a daily basis through the local press, radio, television and our website: www.trafficwatchni.com"
