Buses from Nailsea into Bristol have been diverted because roadworks on the Long Ashton bypass were causing them to run up to 30 minutes late.
Owner of North Somerset Coaches, David Fricker, has been forced to re-route his X54 express service which normally runs at 7.40am each morning from Nailsea Link Road and along the bypass into the city after it became snarled up in the traffic.
Motorists have been facing delays along the bypass due to a £198,000 programme of repairs being carried out to Kennel Farm Bridge by North Somerset Council.
The work started last week and is due to take ten weeks to complete.
Mr Fricker took the decision to re-route the bus – relied upon by commuters – after it was delayed by around 30 minutes, meaning the average 25 minute journey from Nailsea into the city was taking an hour.
The bus has now been diverted along Clevedon Road and up through Failand and down Clarken Coombe.
But Clevedon Road is also being closed this week for four days for roadworks to be carried out.
A diversion has been put in place during the Clevedon Road closure, re-routing all traffic, up along the narrow and windy Belmont Hill.
Mr Fricker said: “I run three express buses from Nailsea to Bristol each morning and in the evening. The earlier buses haven’t been as badly affected but the later bus which leaves at 7.40am suffered severe delays.
“As a result of this we immediately changed the route to go around Failand to avoid the problem area.”
If buses are regularly late they can be reported to the Traffic Commissioner who can impose penalties. Inbound traffic is being diverted off the A370 at the Long Ashton slip road.
