There are several delays on roads near the A1(M) after the Hatfield Tunnel was shut.
The tunnel was closed in both directions this morning due to safety concerns caused by a power cut which affected 76,000 south Herts residents yesterday.
Roads near Hatfield, Welwyn Garden City and St Albans - which are being used to divert traffic from the A1(M) - have all been disrupted, according to Herts Highways.
Two back-up generators are running but these are only for essential services - which is causing the disruption.
"The power outage in the tunnel means that safety features, such as CCTV, smoke ventilation systems, cross tunnel doors and emergency lighting won't be operable in the event of an incident in the tunnel," a spokesman for Highways England told WHT.

"Therefore as a safety precaution, the decision was taken to close the tunnel in both directions while engineers worked to get the power up and running again".
Currently, the diversion information is as follows:
