The original layout, called Sauga Kolmnurk (Sauga Triangle), was a 6.100 km (3.790 mi) long circuit utilising three public roads: Nurme tee, Sulu-Papsaare tee and Haapsalu maantee.

This 3.668 km (2.279 mi) long layout included one of the corners of the original Kolmnurk as well as two, shortened, straights on Nurme tee and Haapsalu maantee.

The 2.173 km (1.350 mi)[5] long layout uses the sections added in 1990 plus a new straight and a chicane.

A 350 m (1,150 ft) long straight on Nurme tee is all that remains of the original 30's circuit.
