Update 6/16
The CDT has closed from Hwy 15 and Hwy 35 (CDT miles 182- 204.5) due to the Trout Fire, in the Gila National Forest. As this is an active growing fire, there is no recommended reroute at this time.

The fire was reported Thursday, June 12, in the Trout Creek area of the Gila National Forest. Driven by hot, dry weather, the fire quickly grew and crossed NM-15 in the afternoon. Command of the fire transferred command to the Gila/Las Cruces Type 3 team Thursday evening. Saturday morning, command will again transfer to a complex incident management team, Southwest Team 4. Resources working the fire include hot shot crews, type 2 hand crews, dozers, helicopters and fixed wing aircraft.

The Gila National Forest has implemented a closure order. (See below)

It is 4.1 miles long, compared to the old route of 3.9 miles, and passes by the Sandoval County Fairgrounds and USFS Cuba Ranger District office.
