In the '60 and '70s some extremists, including
The Economist magazine, suggested that railways were
obsolete and that all the railway lines should be so converted.
This idea was repudiated by most sensible people and some
motoring organisations pointed out that railway routes were
not wide enough to be suitable for main roads.


Here are some examples that I know of:

A22 East Grinstead
,17z
The 'conversion' was a fairly major bit of civil engineering for such a
short piece of road, involving digging out two short tunnels along with
major reconstruction of several roads elsewhere in the town.

A283 Steyning Bypass
,16z
This required a couple of bridges to be rebuilt, but was otherwise fairly
straightforward.

A61/A617 Chesterfield
,14z
This is rather more extensive, and all dual carriageway. Other than a short
tunnel under the town centre nearly all of the route shown is on the
ex-Great Central trackbed.
