Most streets in Port Louis are laid out in rectangular grids, and many are one-way.  Although most roads are in good shape, many streets are fairly narrow as would be expected for a historic colonial town.  Due to the daily influx of workers to business and government offices in Port Louis, day-time traffic can be quite heavy and finding parking spaces a challenge. To cope with increasing traffic congestion, the government has proposed a light rail transit system. Other suggestions have included moving some of the 24 government ministries currently located in Port Louis to surrounding regions, or introducing flexible work schedules. An effort to move workers from the city centre has already started with the construction of the Ebène office tower complex south of Port Louis.  A ring road passing on the east side of Port Louis is also expected to reduce congestion.  Phase 1 of that project was completed in 2013, but in February 2014 the road needed to be closed due to the appearance of a major crack, apparently due to faulty design. Another project initiated to reduce congestion is the construction of a bridge (commonly referred to as the "Dream Bridge") from Les Salines to Roche-Bois, which will span the Port Louis harbor.
