TREASURE ISLAND – City commissioners decided at a Sept. 8 workshop to move forward on a Department of Public Works proposal to make needed repairs to the approaches to Treasure Island's Isle of Capri and Isle of Palms bridges.
Public Works Director Jim Murphy is seeking approval to spend $66,346 for the emergency repairs, which would be performed by Pneumatic Concrete Co. Inc., of Birmingham, Ala.
Pneumatic was the low bidder of three companies that submitted bids on the project.
“This project is to stabilize the embankments (to the bridges) that are there now,” said Murphy. “This is necessary to keep these bridges operational. The stabilization will last long enough until both bridges can be replaced. There will be no work on the structure itself.”
Murphy said due to the degradation of seawalls and seals at the bridges, the approaches have “voids” under the road bed.
The city recently spent $11,820 for a ground penetrating radar evaluation by Infrastructure Preservation Corp. to determine the severity of the problem. IPC identified various locations at each bridge where voids required filling. The filling will be accomplished using a pressure grouting or a flowable sand fill.
Funding for the project is through the Penny for Pinellas. A total of $100,000 was budgeted in 2009-10 to cover it. Following the amount spent for the ground penetrating radar evaluation, $88,180 is available.
“This will stop the bleeding with the voids that have already shown up,” said Murphy.
The estimated cost to replace the two bridges and their approaches is $4 million.
In other action, the commission:
• Moved ahead on a proposal to spend $7,000 for Brotherton Engineering to obtain the most reasonable location and cost for undergrounding of utilities on Gulf Boulevard. The undergrounding project is estimated to cost $5.4 million with $3.77 million coming from Penny for Pinellas funds.
• Authorized city staff to work out a license agreement with the operators of a skimboarding instruction camp on Sunset Beach at the Ringed Bill Gull lot access at West Gulf Boulevard and 81st Avenue. The camp operates on Saturdays from 10 a.m. to noon.
• Moved ahead on a proposal to make improvements to the Treasure Island Central Beach Trail. City Manager Reid Silverboard suggested the plan be discussed more in-depth during an October workshop.
