New lanes and extra signs have been added to controversial changes on a busy commuter route.

Changes made without warning on Glencrutchery Road, Douglas, this week have been causing confusion and tailbacks.

A new combined bus and cycle lane resulted in queues for the St Ninian’s junction building up back to the Grandstand pit lane exit.

There was even more confusion at the other end of Glencrutchery Road where northbound traffic is now directed onto Governor’s Dip.

Highways chiefs insist the measures are aimed at helping traffic flows while Douglas Promenade is one-way northbound.

But overnight on Wednesday/Thursday highways teams were out making further changes, with extra signs installed and lines painted in both carriageways.

A 20mph speed limit has been introduced between the Gate House at Government House and Third Avenue.

As the roundabout at the top of Victoria Road is not currently being used, southbound traffic will continue to travel straight through the junction to Glencrutchery Road, while a left-hand filter lane will serve those wishing to approach Douglas from Victoria Road.

A stop sign is now in place at the top of Victoria Road and motorists wishing to travel from Victoria Road towards Onchan are required to go straight on towards the temporary northbound lane at Governor’s Dip.

Motorists travelling north will no longer be able to turn right into Victoria Road.

Traffic light timings have been increased at St Ninian’s crossroads to help traffic turning left, towards Broadway.

Cyclists using the temporary bus-cycle lane and who wish to proceed straight on at St Ninian’s crossroads must not wait in this lane.

The new layout will continue to be monitored while road users become used to the changes, and will be subject to further review ’if deemed necessary’, said the Department of Infrastructure.

Motorists are asked to be patient and allow extra time for journeys.
