We are on the Dream now. Came down from Fort Worth on Saturday. Went through Houston about 1 pm and aside from the usual slowdowns (too many cars and not enough road), there were three lanes open all the way to Galveston. Coming back, it looks like I45 goes to one lane after you go over the Galveston causeway, and remains 1 lane for a few miles (some backup, but cars were moving). Whatever you do, do not get off the freeway in that area as you will not be able to get back on for miles and the backup on the access road was very bad.
