Some small businesses in Folsom are struggling to stay afloat as upgrades are made to the historic part of the city. Construction has been going on since August and it’s limiting access into several nearby shops. While business owners say in the long run the changes could help them, in the meantime they’re losing a lot of money. The signs say open during construction, but the problem is figuring out how to get inside. Fencing is shutting off entrances to a row of small businesses on Leidesdorff Street in Historic Folsom. The city is upgrading the area for cyclists, widening the road and extending the Johnny Cash Bike Trail.
