DOT Answers: Traffic signal timing fixed at Warwick intersection


Traffic signal timing fixed at Warwick intersection
The Providence Journal – July 29, 2012
Dana Alexander Nolfe


 Q: Since the completion of the new intersection between Routes 5 and 113 in Warwick, there seems to be an issue with the timing of the traffic signal. Specifically, the green left turn signal from Route 113 West onto Route 5 North is short, often leaving several cars after it turns red. Similarly, the left turn signal into the Lowe's and Stop & Shop plaza which was installed at the same time is also short. Can the DOT look into these issues?
   — John, Warwick

   A: In response to your e-mail, the Department has reviewed the operation of the traffic signals at Greenwich Avenue and East Avenue, and at Greenwich Avenue and the Lowes Shopping Plaza. Engineers have made some adjustments to the intersection   operation and timing, which will provide better service to turning traffic.

DOT Answers: Bridge work schedule

DOT Answers: Bridge work schedule 
The Providence Journal-July 22, 2012
Dana Alexander Nolfe

 Q: The bridge at the north end of North Broadway in East Providence will take two years to replace. Why can’t a replacement bridge be built off-site as the Iway was on I-195? Once the new footings are in place the replacement bridge could be put down on this short span.
   Larry B., Barrington    A: RIDOT’s engineers agree that the work needs to happen as quickly as possible in this location. The department therefore has negotiated with the contractor of the Ten Mile River Bridges replacement and plans to accelerate the bridge’s construction.    The two bridges are expected to open to traffic by the end of this year. Other more minor construction work will continue with minimal impact to traffic.    Dana Alexander Nolfe, chief public affairs officer for the state Department of Transportation, answers questions of general interest posed by Journal readers about state roads and other state transportation matters.

DOT Answers: Why did interstate signs change?


DOT ANSWERS - Why did interstate signs change?
The Providence Journal – July 15, 2012
Dana Alexander Nolfe
 
Q: Back in the mid 1960s the interstate highway signs included the name of the state just above the highway number. Sometime around   the 1970s this stopped. Can you tell us why the name of the state is no long part of the signs?
   — Jim C.  
   A: Interstate highway signs display a designated interstate number on a red, white and blue shield. As a part of the original design,   the state through which the highway ran through also was included on the shield.
   The Manual on Uniform Traffic Control Devices (MUTCD), a federal publication put out by the Federal Highway Administration (FHWA), governs the uniform standardization of signing and pavement markings in every state.
   Over time the interstate shield sign has changed simply as a result of several design modifications. The current MUTCD standard does not include state names on the interstate shield.
