King County Parks closed the old railroad trestle on the Snoqualmie Valley Trail at Reinig Road near the town of Snoqualmie after a fire engulfed the base of the bridge on Tuesday.
This is the location where the rail-trail dead-ends on the bridge in the vicinity of the mill pond. Steps lead down from the bridge deck to Reinig Road. Witnesses told the Living Snoqualmie blog that those steps and bridge abutment were on fire.
Bicyclists can avoid the bridge by using a path through the Three Forks Off-Leash Dog Park or exiting the trail at the Mount Si Golf Course.
King County Parks said the bridge will remain closed until it can be inspected for damage.
