Potential Problems with Road Upgrades

Although the process of road upgrading is simple. Nonetheless, you can run into some major problems if you’re not careful with which road you upgrade at the end of the day. I’ll discuss some potential issues here so that you can keep an eye out to avoid them whilst upgrading roads in your own city.

Buildings Might Get Destroyed

There are some negative consequences that you can face if you upgrade the wrong road. Roads have an impact on the buildings that are built around the roads themselves.

If you change the road from a basic 2-lane road to a four-lane road then because the roads are going to be wider, any buildings on their side will be destroyed.

This can be quite a hassle. Because to upgrade your road, you will have to sacrifice an entire building for a commercial purpose. In some cases, this might be used to solve the problem of congestion. However, most times you would like to only upgrade roads that can be safely developed further.
