In 2007 HyderTobin Consulting Engineers were engaged to undertake the planning and design of the N4 Mullingar to Longford (Roosky) Scheme. Due to funding restrictions this scheme was suspended in 2010, following the publication of the Preferred Route Corridor. The Preferred Route Corridor and the Route Selection Report as published in 2010 can be downloaded below.
