VELSEN SOUTH – The Velsertunnel the A22 highway is reopened Sunday morning. According to the ANWB and Rijkswaterstaat traffic was a little after 8 hours in both directions again drive through the tunnel, now a research in the tunnel after 36 hours have been completed.
Friday the tunnel was closed for a few hours a power failure; cameras to keep an eye on things and pumps rainwater drains were not working anymore.
Saturday showed that a combination of a cable fault and a low supply of electricity was the culprit. Those problems were solved, and then all kinds of systems in the night from Saturday to Sunday extensively tested with a positive result.
The next time the tunnel closely monitored, because the problems with the power supply may have affected the software, for example, on some systems. effects Where needed to be replaced.
Pumps
Friday was the Velsertunnel closed.
Due to problems with the power not working the pumps in the tunnel, putting the tunnel tubes volliepen. There is always leaking a little North Sea Water in the tunnel and there is rain water into the tunnel.
The tunnel was Friday most of the day and was closed all day Saturday closed.
Main Cable
Rijkswaterstaat first locates the problem in the energy supply of the tunnel installations. That Saturday was a defect in the main power from the grid of energy.
That problem had to be resolved before Rijkswaterstaat could further search.
Two ferries
After two days with major traffic problems in IJmuiden and Velsen-Zuid, CFP Saturday operator has deployed a second ferry at the end of the afternoon between Velsen and Velsen-Zuid. To alleviate congestion in Velsen-Zuid were cars Free across.
Bus Connexxion went Saturday first by ferry, but were at the end of the afternoon still drive through the Velsertunnel.
Trains
It is unclear whether ambulances (to and from the Red Cross Hospital in Beverwijk) also allowed. The ambulance station and fire station in Velsen-Zuid are anyway affected by the congestion.
It is also striking that the Velser tunnel right next to the Velser Auto Tunnel, encountered no problem. Rail traffic was not obstructed.
