Overview
- The shutdown took effect at 1:00 on Sunday and is scheduled to end at 2:00 on Monday.
- The direct parallel carriageway is closed, along with the A661→A3 on-ramp from Egelsbach and the A3 (from Würzburg) exit to the A661 south.
- Traffic to Cologne is diverted via the A661 toward Oberursel, then via Bad Homburger Kreuz onto the A5 to Frankfurter Kreuz, with local detours to Egelsbach or Darmstadt signposted.
- The closure enables lifting a temporary bridge that will carry traffic during construction of the new interchange structure.
- DEGES says this weekend’s action opens a multi-week modernization, with further restrictions to be announced, reflecting forecast loads of about 181,000 daily vehicles on the A3 and 117,000 on the A661 by 2030.
