2008-12-01 Road is closed 3 miles from the trailhead as of 12/1/08. Road construction also causes further delays Bridger         
2008-11-15 Road is still open all the way. Minor ice on the lower sections above Georgetown, snowpacked but not bad just below treeline. Still passable by any vehicle with decent tires! mtnmike         
2008-11-02 As of today, 2 Nov 2008, the Guanella Pass road was open. There were a few patches of ice, but no big deal for 4WD. There is still construction, but it was inactive during the wknd and thus there were no delays. song_follower         
2008-09-29 As of tuesday September 23, Guanella Pass on the Georgetown Side was closed from 8am to 11am, and 1pm to 3pm. Expect at least 30 minute delays during road open hours to reach the trail head. charlesbhodges         
2008-09-13 Construction zones notwithstanding, Guanella was not impacted by recent storms this last week. Road is free & clear all the way. During the heavy construction on the Georgetown side (scheduled into 2010), I would suggest approaching from the Grant/US285 side if you can. No construction, and the road‘s in good shape! mtnmike         
2008-09-02 Update on construction: The road (from Georgetown) is closed completely Monday-Thursday from 9am-11am and 1pm-3pm. When open, flag crews are controlling the one-lane sections and they are NOT well coordinated. At night, there are two sections controlled by portable traffic lights set at 7-minute intervals. Allow approximately 40 minutes to the TH at night, longer during the day. Flatland14er         
2008-08-13 The road is fine execept for several big potholes. The construction is a pain and so are the one lane road parts where they installed stop lights. The lights take forever to change. stlouishiker         
2008-08-06 Road to the trail head in excellent shape. there are some potholes and washboard areas but the closer you get to the trailhead the easier the road gets. they are doing some construction which may cause 30 minute delays between 9-11 am and 1-3 pm to improve the road. Easily passable in a 2wd. Yalegirl09         
2008-07-04 06-14-08 - Easy drive to the pass with little snow; road in very good shape. Joygo         
2008-05-26 Clear of snow and drivable by all vehicles. Parking lots at the pass have been plowed. BTL         
2008-05-21 as of Monday May 19th still was closed in the morning at the campground although plows were working in the afternoon. jesse         
2008-05-17 Road still closed at campground. skimrg81         
2008-05-04 From I-70/Georgetown, the closure point remains the same. Wisco         
2008-04-21 I think a previous post about Guanella Pass from the north needs clarification. The road is closed just past the campground, which is ~1.5 miles down from the pass, so 3 miles roundtrip. And there are obvious tracks through the woods before the last switchback that avoid going to the parking lot itself. It‘s not that bad. moon stalker         
2008-03-30 From the south, the road is accessible to Geneva Park. The county has plowed a large pile of snow into the middle of the road just past the cattle guard. It looks like a jeep or other short wheelbase 4x4 may be able to squeeze past on the right hand side. covfrrider

2008-02-18 when coming up from Georgetown the road is closed just a little ways past the campground. at least 3‘ of snow on the road, more in some places. hiked almost 3 miles to get to the actual TH. in some places the snow was a foot over the guard rail. keg2008         
2007-12-18 Snow closure at guanella pass campground. Plowed til there. Jcwhite         
2007-11-26 From notice in the Canyon Courier, the road will be closed Friday Nov 30th 2007 thru May 23rd 2008 Also says call Guanella Pass Road Information line at 303-569-3251, ext 2, for updates gsellers         
2007-11-25 Road has an inch or two of hard packed snow from Georgetown to the trail heads. There are signs of plowing to the power plant only. Very icy in spots (morning) and extreme caution should be taken around the sharp curves. I would imagine it will get much tougher to attain after the next snow. krz2fer         
2007-09-19 Grant side is the best way to miss the construction, until "phase 3" starts in 2011. Got an update from the manager, the phase from Georgetown to the Xcel power plant ends in 2010 so that side will be busy for a while yet. Reference - gsellers         
2007-08-02 Road construction is still taking place on both sides of Guanella Pass. Delays are running between 10 and 30 minutes. If you are climbing on a weekday try to get to the trailhead before 6am because that's when the road crew begins work. They take the weekends off so you shouldn't have much to worry about then. The Grant side may offer fewer delays during the week because most of the work is taking place on the Georgetown side right now. Cruiser         
2007-07-11 Road is clear to trailhead. There is road construction on the way up. Be prepared to stop and wait for a pilot car to take you through the construction area. We waited 10-15 going each direction. You may want to get out and stretch and maybe even talk to the flagger guy (he must be bored out of his mind!). Spacelepor         
2007-07-09 Climbed Bierstadt July 7, 2007. Got a 730am start due to a rollover accident on the road to the pass, but still finished in 6 hours flat as I was hiking with a first timer that smokes a pack a The only snow is the well-known packed trail about 600 ft from the summit. Holliewd
