Main Street Business Thrive After Opening of New Bus Lines
Although limited parking due to construction on Main Street might be expected to reduce restaurant patronage, this spring’s average revenue at local eateries and other retail businesses has actually increased overall since the opening of the new bus line. According to reports from local business owners, sales have increased as much as 40 percent compared with the same period last year. While this recent escalation in sales may not be directly attributed to the access provided by the additional lines, business owners seem generally pleased with the results of the long-awaited project. For those shoppers who visit Main Street in cars and rely on the availability of parking, construction is expected to be completed by the end of April.
