Vehicles will detour to Palmetto Park Road and cross the Intracoastal using that bridge.
Officials say the closing is needed to replace a 15-foot section of concrete sidewalk above the east machinery room.
At Parker Avenue
For the next month or so, drivers coming into downtown West Palm Beach will have to find a route other than heavily traveled Okeechobee Boulevard.
Since July 11, Okeechobee Boulevard has been closed at the railroad tracks located on the west side of the Tamarind/Parker avenues intersection.
Palm Beach County engineering road crews are installing a second left-turn lane onto northbound Tamarind Avenue, which will require repositioning the crossing gates.
Crews are also adding a westbound through-lane on the north side of Okeechobee Boulevard west to the Australian Avenue entrance ramp. This work will require temporarily closing the southern access into the Marriott West Palm Beach Hotel. Hotel visitors are to use the north entrance, Clearwater Park Road.
Okeechobee Boulevard is expected to reopen to traffic at the railroad tracks by August 15. During this period, eastbound traffic on Okeechobee Blvd. will be diverted at Australian Avenue north to Banyan Boulevard and south to Belvedere Road. Westbound traffic on Okeechobee will be detoured at Tamarind/Parker avenues.
