The affected section of the A7 motorway runs from the Hamburg-Stellingen junction to the Hamburg-Heimfeld junction.
The main closure is set to begin from 10 pm on Friday, December 5th and then continue for 55 hours. The closure is expected to be lifted on Monday morning at 5 am on December 8th.
The closures of the Hamburg-Stellingen, Volkspark, Bahrenfeld, Othmarschen, Waltershof and Heimfeld slip roads will begin at 9 pm on Friday.
During this time, through-traffic will be largely diverted via the A1, A21 and B205 motorways, with detours marked by signs.
Coming from the south, drivers are to be diverted on the A1 from the Buchholzer Dreieck/ Horster Dreieck via the Maschener Kreuz junction.
Those coming from the north, are to be directed on to the B205 from the Neumünster-Süd junction.
There may also be traffic jams on the A1 in front of the Norderelb bridge, because traffic restrictions have been imposed on the motorway bridge, especially for trucks, since mid-March.

The closure is related to a plan to expand the motorway from six lanes to eight lanes, as well as adding improved noise protection infrastructure. The two-kilometre-long Altona noise protection tunnel is scheduled to be completed by 2028.
