The West Link (Swedish: Västlänken) is an underground railway tunnel under construction in Gothenburg. The purpose of the project is to increase capacity and reduce travel times. Three new stations will be built – Gothenburg Grand Central, Haga and Korsvägen – the latter two being underground stations. Of the 1.02 million people (2018) who live in Greater Gothenburg (1.7 million in Västra Götaland County), 450,000 people live outside the Gothenburg municipality. Approximately 175,000 people in the region commute to or from Gothenburg Municipality daily.
