Northbound lanes at the Port Road underpass will be temporarily closed for two nights each month between June and August for monitoring works. Monitoring will involve survey and inspection of the Port Road underpass to ensure it is performing as expected now that we have opened the road.

Please see map below for more information on the detour.

Some noise can be expected, but we’ll try to keep these disturbances to a minimum. Please follow traffic management directions while work is in progress. In addition, we will contact you if the work directly impacts your property. Detour information will be provided on VMS boards in your local area and on our website. Weather conditions may affect our progress.
