The construction of the new motorway bridge between Penzberg and Iffeldorf has been completed.
Now we continue with the state road.
It is now clear that traffic on the access and exits to and from the A95 should be regulated by traffic lights.
But there is a sticking point: how should cyclists cross the dangerous point?
Iffeldorf/Penzberg - It's a dangerous passage: The cycle path from Iffeldorf to Penzberg crosses the A-95 exit from Munich and the slip road towards Garmisch shortly before the motorway bridge.
A place where many motorists turn off to Penzberg in the morning during rush hour and many cyclists are also on the road.
An Iffeldorfer counted around 30 cyclists there on a working day between 7 a.m. and 8 a.m. alone.
In the local council there was recently talk of a dangerous, intolerable situation.
Conversion of the state road: traffic light regulation instead of roundabout
Now changes are imminent.
After completion of the new motorway bridge in autumn, it is now the turn of the state road between Iffeldorf and Penzberg, as has been announced for a long time.
The conversion should take place this year, as Andreas Lenker from the Weilheim State Building Authority said when asked.
It was originally planned to build a roundabout at the entrances and exits on the Iffeldorfer and Penzberg sides.
As reported, the plans were buried a good five years ago due to problems with the land acquisition.
For this reason, car traffic should in future be regulated on both sides at the entrances and exits using traffic lights.
The sticking point: How are cyclists guided past the entrance and exit
A sticking point is the question of how cyclists will be guided past the entrance and exit of the motorway on the Iffeldorf side in future.
There are different answers to this.
State building authority favors changing sides and traffic lights for cyclists
"Our focus is: The cycle path should lead consistently and safely across the junction," says Lenker.
His “preferred variant”: cyclists from the direction of Penzberg drive, as before, on the north-eastern side under the bridge.
But just before the junction they change to the other side of the lane.
A separate traffic light would be necessary for this.
On the south-western side they would then be directed to Iffeldorf via a (not yet existing) cycle path.
According to Lenker, the question is whether an additional center island is required.
This would be the case if Autobahn GmbH provided a new fully-fledged turning lane for drivers who wanted to turn right onto the Autobahn in the direction of Garmisch.
Cyclists would then have to use a turning lane when crossing the state road.
Lenker himself would prefer a solution without a fully-fledged turning lane and without an additional center island.
This, he says, would be the “bike-friendly option.”
Another solution is preferred in Iffeldorf: Radler-Tunnel
In Iffeldorf they are promoting a completely different solution: the cycle path should stay where it is.
At the junction on the Iffeldorf side, however, it would make a curve and end in a cycle tunnel that would lead under the entrance and exit.
Cyclists and motorists would no longer get in each other's way.
The A95 exit near Schäftlarn is cited as a model.
A tunnel was created there, although the volume of traffic and cyclists is lower.
In Iffeldorf one still hopes for a rethink.
Lenker confirms that the tunnel variant was discussed.
The bike path, he says, would have to be lowered relatively far before the junction.
According to Lenker, this would mean that cyclists would have to cycle back a bit to Iffeldorf on the cycle path in order to take the tunnel route.
According to him, there is a risk that they will then cross the junction on the state road.
The state road is to be reconstructed this year
Either way, the work on the state road should take place this year.
“We want to start as soon as possible,” says Lenker.
He estimates the work will take three to four months.
The full width of the provisional surface of the state road to Untereurach will also be renewed in the process.
It is still a matter of negotiation who is the client: the state building authority or Autobahn GmbH, which will bear more than half of the costs at the junction.
