In a place with essentially nothing but narrow two lane roads, no bike lanes or sidewalks, a little wider might serve some good. Adding a turn lane and a bike lane would free up tons of traffic.
If the highway increases in size, then more off ramps or more lanes in the off ramps are needed, which in turn need more lanes on the main street that connect to the off ramps. It's basic filtration system dynamics.
I'm not talking about highways, I'm taking about roads connecting suburbs etc. The only way I can get to work. They're terrible and only accessible to cars.
My town wants to widen a section of road near me. It's the only part of the road with only one lane each way
I'm torn. I know widening the road won't help traffic (right now that narrow bit reduces through traffic, making it a nice bit of road to drive) but if they do widen it, they will also add cycle lanes.
