The marked section should be avoided. At least with 23 mm wide tires on even narrower rims. The asphalt has been lying here for over 50 years and is only brittle and covered with gravel. Unfortunately, that doesn't make it any better. Just stay on top of the dam.
Broke off, had a flat tire and was only traveling with light luggage. The police then helped me get back on the street. Thanks to the Groß Gerau police.
