BE careful of how close you get to these trucks. They haul cut timber trees and are always in a hurry. Good tying down the load is questionable sometimes. I had an experience once when tress came flying at me and I was going about 600 mile per hour. It can be killing. The truckers speed and have little regard for the risk they convey.
The street has parking for 2 hours along Central. If you stay longer, a ticket will be issued. In the next block in the rear is a garage lot that charges some fee, but probably not more than 50 cents an hour. Other places have meters with a quarter an hour. Read and be aware
Although Hot Springs isn't a large town, it only has one main street through the middle of it. Just south of town, a limited access highway (US 270 aka MLK Expressway) crosses the main street (Central Avenue which is also Arkansas Route 7). At this location there are multiple lights (one on each side of each lane of the highway to allow people getting off the highway to turn onto Arkansas 7) and also a constant traffic jam at almost all hours of the day and evening because lights were used to control access to the highway instead of using merge lanes.
