The tunnel near the Morse Boulevard bridge reopened at about 8 a.m. Tuesday after the latest round of flooding.
The tunnel had been closed for about an hour beginning at 6:45 a.m. The tunnel is passable for golf carts.
Flooding at the tunnel has been a problem since last September’s Hurricane Irma.
Pumps have been running continuously, trying to bring down the lake level.
Last week, Sam Wartinbee of Commercial Property Management predicted several more months of pumping will be necessary.
