parking across University Parkway next to LES. That's always a logjam. Seems like a relatively easy and inexpensive improvement.
Even better would be to also build a wide pedestrian bridge over University Parkway. Let the people and the traffic flow!
Another easy and inexpensive improvement would be to add an exit directly onto Canyon Rd from LES parking (for basketball games).
I would also consider to build a driveway along the east side of LES to connect LES parking directly to Stadium Ave. (for basketball and football games).
More entrances and exits and moving pedestrians over (instead of across) the main roads would greatly improve the parking experience and traffic.
