BOISE -- A street in downtown Boise is partially blocked as crews deal with a section of road that collapsed overnight.
According to Boise Police, the sinkhole opened at 9th and Main streets after a geothermal line broke at about 3:30 a.m.
The broken line sent water spilling out underneath the road, causing the sinkhole. The collapsed area is about four feet across.
Main Street was blocked between 8th and 9th streets for several hours. The far left lane has since been reopened, but commuters should expect delays in the area.
Crews have turned off the water, but lane blockage will remain until the damaged road can be repaired. Boise Police and Ada County Highway District crews are on scene.
An ACHD spokeswoman said Main Street is expected to be restricted to one lane through the evening commute. Drivers should avoid the area if possible.
Crews expect the road will be repaired and all lanes reopened by Friday morning.
