A &apos;confusing&apos; and &apos;badly signed&apos; diversion which apparently leads drivers into the exit of a one-way system could be one of the most confusing Devon has ever seen.
The diversion around a student flats development at the former site of Quintana Gate has motorists scratching their heads over a sign telling them to turn into Mary Arches Street from Bartholomew Street.
Drivers have been baffled by the confusing westbound diversion - which may not actually exist.
One driver described the route as "ridiculous."
"I thought that I had missed a diversion sign.
“It’s not until you get right up to the Mary Arches junction that you realise there are diversions in place and by then it’s too late.
Another driver, Zoe Stevens, said: "I had noticed there was a road closed sign with an arrow last week, but I could not see it on Monday morning, so I presumed the road had reopened.
"When I drove along by the Picture House, there were some roadworks around but no sign that the road was closed, until I turned the corner and there were no entry signs.
"I pulled into a junction and turned around, and it was only when I was doing this that I noticed two other motorists turning around in other previous junctions. I guess they had done they same thing!
"It’s very confusing, the signage isn’t clear at all, and it’s obviously affecting a lot of other drivers too."
So how exactly do you tackle the route?
It&apos;s actually very simple - despite the signs in place to the contrary.
A spokesperson for South West Water, who have put the closure in place, say it is in fact a one-way system and a suspension of parking rather than a complete closure.
It means drivers can actually continue straight on from a westerly direction onto Bartholomew Street East and through to Fore Street and New Bridge Street.
It is only easterly drivers who have to divert to Fore Street and Mary Arches Street to reach Bartholomew Street West.
It isn&apos;t known why the turn-left sign is in place, nor the road closed sign.
The traffic change is expected to continue until Friday December 15.
The works involve the movement of 40m of water mains for a large student accommodation development.
