How does the City build wide roads when there's no room?

What I see there is a large number of extra-huge roads.

And whose idea was the roundabouts on three-lane divided highways? Those will keep the body shops and ambulances busy. Does anyone else not see a problem with that?

WUT? Please drop Lat/Long location pin in here so we can see an example of a roundabout on a 3-lane divided highway.

They were all over that map in the first link. Look at the green dots on the red lines. Everywhere.

Besides that, they're making nearly all the residential roads (that will only ever be residential) six lanes. That map is terrible. They need to go back to the drawing board on this.

First of all, those aren't "freeways". They're residential streets. Roundabouts are actually much better than traffic lights for vehicle flow, especially in dense suburban areas.

So? Neither is Preston Road. Neither are any of the tollways around north Texas. That doesn't make them any less busy, fast moving, congested, or noisy.

Yes, roundabouts have their advantages but not with so many lanes.

Can someone explain why they would dedicate 6 lanes for developed residential neighborhood streets?

Because thoroughfare plans in DFW are crazy oversized. Preston needs 6 lanes - it carries 60,000 cars a day. Generally, the rest? Less than 1/3 - to half of that at most.
