Here in the UK stroads were pretty much eliminated everywhere during the 70s and 80s by building bypasses. A bypass is a road built in an arc around a town to divert through-traffic away from the town centre, leaving only the slow street traffic (mostly people coming from outside town to shop). Larger towns have more complicated arrangements, but the pattern is the same: keep through traffic away from the streets in the business area. The business area itself is often pedestrian-only and always has restrictions to make driving through it a slow business.

Typical example: https://www.google.co.uk/maps/@50.9997356,-0.9166437,14.25z?...

More complex example: https://www.google.co.uk/maps/@51.1101752,-0.1713974,7297m/d... . Note the M23 on one side, Crawley Avenue on the other, and Peglar Way right in the middle. All of them serve to route traffic around the town centre instead of through it.

In many cases you can see how the original through-road (sometimes dating back to Roman times) had the bypass patched on; without the bypass the "High Street" would have been a stroad.

(Fans of The Hitchhikers Guide to the Galaxy may recall Arthur Dent's cottage being demolished to make way for a bypass. This was an issue: the nature of bypasses meant that building them often required the demolition of nice little cottages on the outskirts of small towns.)
