For three days, beginning September 8, 2009, the move to the new South Entrance road will begin. No public vehicle traffic will be allowed to access Mather Point and no non-commercial vehicles will be allowed access to the plaza at the Grand Canyon Visitor Center. The rim trail will allow pedestrian access to Mather Point from Yavapai Observatory. The access closing is expected to be over no later than September 11, 2009. If you choose to drive your own vehicle into the park you will need to watch for signs and flaggers. Expect parking to be very limited during this time.
For those familiar with the Grand Canyon and the area in question, you will notice a huge improvement in the congestion around Mather Point. I have been up there on days when vehicles were parked on both sides of the road for more than a mile west of Mather. The plan, when complete in December, will provide parking for more than 600 vehicles and commercial tour buses.
