Expect Major Traffic Delays: Alt 19 at Dunedin Causeway

Drivers should expect some impacts to traffic at one of Dunedin's busiest intersections through June.

A $2 million construction project to install 48-inch piping along a water main underneath a significant stretch of Dunedin Causeway across Alternate U.S. 19 and toward Cedar and Curlew creeks has reached the critical intersection.

Alt U.S. 19 at Curlew Road/Causeway Boulevard will reduce to a single travel lane in either direction; signal lights will be off; and Pinellas County Sheriff's deputies will direct traffic 24 hours a day for four weeks starting May 28.

So far, the project, which began in February, caused relatively minor traffic issues on Dunedin Causeway, said Tom Burke, an engineer with the city.

But, "those impacts are going to get considerably more serious at the end of the month," he said.

Drivers, pedestrians and bicyclists can expect major delays through the end of June.

"Peak times will be considerably slow," Burke said.

The following is a breakdown of traffic impacts over the next four weeks:

PHASE I

North-South Traffic on Alt U.S. 19

• Westerly north-south lanes of Alt U.S. 19 will be closed.
• Southbound drivers (traveling toward downtown Dunedin/Clearwater) will be shifted into the northbound lane.
• Northbound drivers (traveling toward Palm Harbor and Tarpon Springs) will be shifted to a merge lane.
• Traffic signals will be turned off and deputies direct traffic through the intersection.

East-West Traffic on Curlew Road/Causeway Boulevard

• Eastbound drivers on Causeway Boulevard wanting to make a left turn toward Palm Harbor will not be allowed.

Bicyclists and Pedestrian Traffic

• Pinellas Trail traffic will be diverted along the south lane of Curlew Road/Causeway Boulevard and the east side of Alt U.S. 19.

PHASE II

North-South Traffic on Alt U.S. 19

• Easterly north-south lanes of Alt U.S. 19 will be closed.
• Traffic signals will be turned off and deputies direct traffic through the intersection.

East-West Traffic on Curlew Road/Causeway Boulevard

• Westbound drivers on Curlew Road cannot make a right turn onto Alt U.S. 19 to go toward Palm Harbor. 
• Westbound drivers on Curlew Road may only continue west onto Causeway Boulevard or make a left turn to drive south on Alt U.S. 19 toward downtown Dunedin and Clearwater. 

Bicyclists and Pedestrian Traffic

• The Pinellas Trail will be closed in certain areas and traffic will be diverted.
