Hi gang, the path is open but the crew doing the paving moves along it during the day and then picks up where they left off the next, so closure points are moving. Last Friday (9/5) we had to detour at the corner of Barranca as they were paving there (we were s/b on Harvard and were going to enter the trail there). We had to continue down Harvard and get on at Alton. Today, (9/8) we got on at Barranca but we had to exit at the Barranca bridge and make a loop around the skate rink to get back to Harvard. We went further down harvard and entered thru a park south of Alton. On the way back to Tustin, they now had the path closed down at Main (it was open only 40 minutes earlier--sheesh). On top of all this, there is road repair around the area too, so even detouring off the path is a bit of a hassle.
Elvo, as of today, you can jump on anywhere west of the 405 w/o having to get off the path. I only saw path asphalt prep scarring at Campus. Nothing west of that either on Bayside portion or cliff side.
