The reality of the Mansfield & Ashford Regeneration Route (MARR) is different to that stated in your article (Regional spotlight 14 April). MARR provides a bypass to Mansfi eld but its contribution to improved east-west transport links is limited.
The route stops many miles short of the A1 and the remainder of the A617 eastwards is on substantially unimproved county roads.
It also fails to link the A60 north-east to the A1, the A617 north-west has two major bottlenecks before the M1, and the new junction with the A38 is problematic.
Nor does MARR effectively serve regeneration sites.
It passes entirely through agricultural green belt, avoiding the brownfield sites. This new land is being promoted for speculative development while important local brownfied sites remain neglected and existing business parks are substantially vacant.
