What do you see when you look in the rear view mirror? How do you respond when someone cuts you off or tailgates? As your mom may have told you as a kid, two wrongs don’t make a right. You are in complete control of how you respond when someone isn’t as polite as they could be on the road.
According to the National Highway Traffic Safety Administration, two-thirds of all traffic fatalities involve behaviors commonly associated with aggressive driving. Although speeding is the most common behavior, anything that places other people, vehicles, or property at risk is considered aggressive driving. Most actions connected with aggressive driving are illegal.
Iowa has many small bridges in need of significant repair or replacement, but no one wants to see a “road closed” sign on the road ahead. Long-term road closures can be common on traditional bridge projects where an existing bridge is replaced with a new bridge. There is an innovative method that the Iowa Department of Transportation has been using for small bridge replacements which uses culverts constructed inside aging bridges. This method allows traffic to keep moving and eliminates the need for maintenance for decades to come.
Iowa DOT engineers are looking at aging bridges, mostly on rural two-lane roads, to see if they can be replaced with a box culvert that fits under the existing bridge. For bridges that meet the criteria, a concrete culvert is cast in place underneath the existing bridge or the culvert can be precast and slid into position underneath the existing bridge. When possible, precast concrete box culverts are cast at manufacturing facilities and shipped to the construction site, saving some on-site work time for the contractor.
Independence Day is upon us and, in case you haven’t heard, commercial fireworks are now legal to sell in Iowa. Many cities and towns still ban the use of commercial fireworks inside the city limits, which might make people think about moving the light show to another location.
