Copy shortlink: Supporters of the Rush Line bus rapid transit project say it will transform spotty public transportation service in the east metro, especially for a rising number of people who live in poverty and those without a car. But a budding group of skeptics are asking whether it's wise to forge ahead with the project, which would connect Union Depot in St. Paul to White Bear Lake, as people continue to work from home in the post-COVID-19 economy. And others worry that frequent bus service — every 10 to 15 minutes during rush hour — would compromise the small-town feel of downtown White Bear Lake.
