Yes, highways can help reduce traffic jams. They offer alternative routes, which can ease congestion on smaller roads. Highways are designed to handle more vehicles, so they can improve the flow of traffic. Plus, they usually have fewer intersections, which means less stopping and starting. This can make travel faster and more efficient.

No, highways might not always reduce traffic jams. Sometimes, they can lead to more cars on the road, which can actually increase congestion. The construction of highways can also cause temporary traffic problems. If not planned well, highways can become bottlenecks themselves. Plus, more highways might encourage people to drive more, leading to more traffic.
