Q: What's the status of fixing the S curve on A1A in Deerfield Beach?
Bob Wilkie, Deerfield Beach
A: Construction is set to begin in July 2015.
Plans call for resurfacing A1A as well as adding bike lanes and continuous sidewalks from the Broward/Palm Beach County line to Southeast Third Street. Drainage will also be improved.
The city is working with the Florida Department of Transportation to see if some of the improvements planned as part of a larger future project can be done at the same time.
Those improvements include adding a stop light and crosswalk on the north side of the S-curve and realigning the intersection at Hillsboro Boulevard and A1A.
Q: Drivers on eastbound State Road 84 make U-turns at Southwest Fourth Avenue at the same time drivers on Fourth are turning right to go west on S.R. 84. They nearly collide every time and slow down drivers in the left turn lane who want to turn north onto Fourth. Also, why doesn't 13th Street have left turn arrows at Andrews Avenue?
Kim Holtzclaw, Fort Lauderdale
A: The issue of U-turns vs. drivers turning right on red is a common occurrence in South Florida.
As roads are reconstructed and medians between signals are eliminated, there's a greater demand for U-turns at intersections. Engineers try to address the problem by increasing the length of left turn lanes at adjacent intersections and by providing longer green lights for left turns and U-turns.
"While sometimes U-turns are restricted, the justification is usually because of these factors: inadequate view of oncoming traffic, [difficulty] for drivers to make a U-turn in a single manuever, a right turn signal that would conflict with U-turns, or a high number of left turn crashes," said Andrew Sebo, a Broward traffic engineer.
The intersection is under the state's control since S.R. 84 is a state road.
At Andrews and 13th, the county found traffic volumes last year didn't meet minimum requirements for eastbound and westbound left turn lanes. In most cases, drivers turning left were able to clear the intersection within a single signal phase. Sebo said the intersection of Northeast 13th Street and 15th Avenue has left-turn arrows, but traffic is much heavier than at 13th and Andrews.
Q: When driving south on U.S. 1 at Linton Boulevard in Delray Beach, only three or four cars turn left before the light rapidly changes red. Any chance of extending the left turn arrow?
Ernie Halle, Highland Beach
A: State engineers observed traffic at the intersection twice last week during midday and afternoon rush hours and found all vehicles waiting to make southbound left turns were able to do so during each signal cycle.
So no timing changes are recommended. But officials say they will monitor the intersection and re-evaulate it once a nearby shopping center is opened.
