I rode it last on July 4th. There are a few expansion cracks that would definitely be scary on a skateboard. These are mainly on the top and east end switchbacks. That pic above is the west end, which would likely be a much better area for lonboard attempts.
Here's an email I recently rec'd regarding the project. The Glade Park area mentioned is at the top of the east end entrance:
While the re-paving of the road through the Colorado National Monument is going on, I will attempt to provide regular, weekly updates as to what you may expect to find.
The road project in the Monument will begin next week (7/10) however, not much is expected to happen for the week other than preliminary work that includes getting the equipment to be used in place. After hours riders should not encounter any serious delays. The plan is to use a re-cycling of the old pavement method. They will tear up a lane of asphalt for perhaps about 1 mile, then tear up the other lane. After that, they will prepare the road base. This will leave for any given time, the possibility that you will encounter a section of road for up to a mile that is only compacted gravel. After the road base is prepared, they will then lay down the re-cycled asphalt. At any given time, there will always be at least one lane of the road open. All motorists and cyclists will be REQUIRED to stop and wait until a "pilot" car that will lead the traffic through. Again, this will primarily occur during the working hours of the day.
The re-paving work will begin on the road that goes up to Glade Park, at the Colorado National Monument Entrance sign. It will proceed down the road to the intersection with the main Monument road above the east entrance, then proceed west. This means that for a 1 - 2 week period, those cyclists who like to ride the Little Park - Glade Park - Monument route will encounter construction. Once that section of road is completed however, this route will be the best way you can avoid construction until the project is completed.
Construction will not occur on the weekends, but you can expect to find some sections of gravel. They will try to leave both lanes of any section of road under construction open for traffic over the weekends.
One other bit of information to pass open: When the entrance stations are open, all motorists and cyclists are required to stop at the station (there is a stop sign there with a flashing light) not only when entering but also EXITING the Monument. Officials have reported some cyclists not stopping. Each station has now been equiped with a video camera to record violators. We have been warned that both motorists and cyclists who are caught will be issued a citation. PLease cooperate with the Park officials. A few cyclists who ignore the rules and just blow through will certainly not help our overall relations with the Park officials.
