Translation:There are many small houses along the street.
Many streets in northern England have "gate" in the name (Gilesgate, Kirkgate, York has Whip-ma-whop-ma-gate which connects Colliergate and Fossgate). This is not because the cities had walls with dozens of entrances but rather because the streets were named by Old Norse settlers during the Danelaw. The only other regional word that I can think of with such an obvious connection to Swedish is the dialectal "barn" for "child".
Väg is road, gata is street. I believe that there is some interchangeability between them in the same way that road and street can often be exchanged in English but essentially väg is a more major road (it also means "way" in terms of "the way is long and treacherous") and gata is a smaller road.
Mods and/or native speakers please correct me if i have misunderstood! :)
