The T'Railway Provincial Park closure has been extended from Gander to Mary March Brook, approximately 45 kilometres west of Badger.
Monday's heavy rain caused damage and the section of the T'Railway is closed to all users.
The provincial government is reminding the public that using vehicular traffic on the T'Railway to avoid road closures is illegal and extremely dangerous.
Users of the T'Railway Provincial Park are advised to use extreme caution as other areas of the trail may be affected by recent heavy rainfall.
