A 1.906 km street circuit (blue outline above) which was first used in 1958 for motorcycle racing, through
to 1965.
In 1974, and after needed track surface repairs, motorcycle racing resumed, and for 1976 the track
was extended to 3.020 km (the red outline was taken on the above map). This was used through to 1978,
when three race meetings were held on the track.
