A Norwegian mountain circuit known as extremely steep over Tronaasen where historical events are the Monte Carlo Rally’s in the 1930's starting from Stavanger. Real public roads 12.3 km (7.6 miles) Sirnes-Tronaasen-Lendemoen (tronaa46).

Why exactly 1946?

The main road along Lake Lunde Sirnes-Tronvik took over the old railway route and thus the oldest possible time (1946) to simulate a fantasy race over these spectacular roads thus contains both old and new road, including the then disused old road over Tronaasen, where quickly grew back with grass and was not used until 1973 as a bypass.
Todays 2010 GPL-version (tronaas) is 13.1 km, most of this has asphalt. The new 1946 version is all over narrow gravel roads, 7 tunnels, some bridges, 12 hairpins and even grass at some parts of the uphill. Hairpin one, is a fantasy turn at the space available graveled up for the occasion, then 8 hairpins uphill and 3 hairpins downhill. Pitlane (fantasy) is in the only possible place that is large enough, a field by Lendemoen that could be done.

The gravel is set to surface type 3/curbs. Short sections have also surfaced type 4 and 5 that are extra slippery. The grip is better than real, and I think the grip fits well to make the track nice to drive.
I can share this GPL-track with the community and expects to be completed during this year. :beta:

Here is a demo that focuses mostly on some of how a real road is made in GPL.

Sounds great, looking forward to it. Your first Tronaasen is one of the most challenging tracks in GPL

This is fascinating.  I never realised just how much work went into putting these tracks together.

Myself,  and I am sure many others, just head to the track download site and take their pick without a second thought as to where it came from.

Thank you very much Bjorn and all you other track builders out there.  I guess this is part of what makes GPL great!

I am now very much looking forward to your new version of Tronaasen as I loved the old one, a real challenge.
