A residential street in Northeast Colorado Springs is closed because of a large sinkhole that appeared Monday afternoon.

The City of Colorado Springs has closed Mariposa Street between Mountain View Lane and Magnolia Street (southeast of Austin Bluffs Parkway and Nevada Avenue) to repair the sinkhole.

The sink hole was reportedly 15 feet wide and 12 feet deep, according to a city representative.

There was no estimated time of repair.

The city says they don't know exactly what caused the sinkhole to open yet, but they are reaching out to the U.S. Bureau of Mines as a 'precaution' to evaluate the situation.

There are old coal mines in the area, which could have contributed to the sinkhole's opening.
