WARNINGS have been issued of possible traffic delays as Colchester half marathon participants will be running through ongoing roadworks.

The route of the event on March 24 includes going through Ipswich Road roadworks.

Contractor Eurovia and Essex Highways said in an online statement: “This event will be making its way through our works and we are working closely with the council to make sure this event runs smoothly.

“Eurovia is helping out with some of the traffic management needs for this event as a small contribution to the community while our scheme works are taking place in the area.”

Workers had to fully close part of Ipswich Road, between Fenwick Drive and the Ipswich Road roundabout, due to safety issues.

Drivers were ignoring all of the advance warning signs and driving dangerously.

Highways workers added: “They then put themselves, the public and the workforce in danger by driving on the wrong side of the road up the open section to the Ipswich Road roundabout causing traffic to stop and avoid this dangerous act of driving.”

The section of road is now fully closed until March 15.
