SALT LAKE CITY — Drivers looking to avoid Parleys Canyon because of a fire burning along I-80 on Saturday may be tempted to check out Google Maps or another smartphone map app to skirt the traffic troubles, which may suggest Guardsman Pass as the better way to go.

But if you drive an oversize vehicle, those services could very well steer you wrong. 

Google Maps says Guardsman Pass? Pass, if you’re in a big truck

Google Maps, Siri and other electronic services sometime suggests Guardsman Pass, a narrow road that crosses from Park City to Big Cottonwood Canyon, as an alternative to I-80. If you’re in a passenger vehicle and you’re driving during fair weather, that advice might work out just fine. 

Update: This restriction is still in place. No semi trucks or other vehicles pulling trailers over Guardsman Pass, SR-224/SR-190 and Pine Canyon Rd. Consider using US-189 or I-84.

However, if you drive a tractor-trailer or other oversized vehicle, Google Maps’ advice to take Guardsman Pass will cause you trouble. The narrow, winding, high elevation pass also includes sharp switchbacks virtually guaranteed to cause a semi to jackknife. 

Instead, the Utah Department of Transportation advises taking I-84 through Weber Canyon or US 189 as alternatives to I-80 while the fire impacts traffic.
