Agenda 03/13/2012 Item #16A73/13/2012 Item 16.A.7.
EXECUTIVE SUMMARY
Request Board approval to post load restrictions of "Single Unit Truck; 31 tons" and
"Combination Truck; 34 tons" on bridge numbers 030138, 030139, 030140 and 030141 east
of S.R. 29 on Immokalee Road, Project Number 66066.
OBJECTIVE: In the interest of health, safety and welfare of the traveling public, to
immediately comply with Florida Department of Transportation (FDOT)/ Federal Highway
Administration (FHWA) notification by posting weight limit restrictions on four Collier County
bridges. Also, the County will pursue studies to determine measures to lift these restrictions via
rehab, repair or replacement.
CONSIDERATIONS: On January 25, 2012, FDOT notified Collier County that these bridges
have to be load restricted and posted within 30 days. Bridge numbers 030138, 030139, 030140
and 030141 are respectively 4.5, 6.0, 6.5 and 7.0 miles east of S.R. 29 on Immokalee Road in an
agricultural area east of Immokalee. Subsequent to this notification county staff requested that
FDOT review its findings on the Immokalee Road bridges. BCC approved posting on February
14, 2012, Item 16A10. On February 23, 2012, FDOT notified staff that the limit on Single Unit
Trucks could be raised from 29 tons to 31 tons and that limit on Combination Trucks could be
raised from 33 tons to 34 tons on the Immokalee Road bridges.
Bridge inspections are a federal program handed down to the FDOT to administer. In the past
year FDOT has been completing load rating on all the bridges under their inspection per FHWA
direction. To accurately determine a load rating requires record drawings. For a great number of
the oldest bridges, record drawings do not exist. In the absence of record drawings estimates are
made based on physical measurements and visual inspection. Based on the fact these are short
span bridges with no visible signs of damage from heavy loading, FDOT re- evaluated them and
determined to revise the posting. Staff is continuing to investigate the condition of the bridges
with focus on rehabilitating measures to remove the weight restriction posting.
Realizing that load limits on bridges negatively impact trucking operations, it is important that
the county act quickly to have the load limit reductions minimized or removed. Knowing that the
bridges have performed satisfactorily under the existing loads over the years without visible
signs of failure, the county could be successful in this effort. At the same time the county needs
to keep in mind that these bridges were never designed for today's truck traffic. Staff has
requested that FDOT load test these bridges, but this will take time. Staff will also arrange to
have a Structural Engineering Consultant review the load rating calculations; perform an
inspection by exposing deck reinforcing steel to determine its size, spacing and condition; and
recalculate the bridge load rating based on their findings.
FISCAL IMPACT: The estimated $2,000 cost of installing signs will be from the Road and
Bridge Fund 101, Traffic Operations. The estimated $75,000 cost to perform studies to
determine the course of action to lift the weight restrictions on these bridges will be funded from
the Bridge Program Project 66066 in the Gas Tax Fund 313. It may be necessary to shift
priorities in the bridge program to address major repairs or replacements.
The future maintenance cost of this item is $1,000 every seven years for replacement of sign
panels.

3/13/2012 Item 16.A.7.
GROWTH MANAGEMENT IMPACT: These bridges are currently inventoried in the Collier
County Bridge master list.
LEGAL CONSIDERATIONS: This item has been reviewed and approved by the County
Attorney's Office, is legally sufficient for Board action and only requires a majority vote for
approval —SRT.
RECOMMENDATION: Request Board approval to post FDOT/FHWA mandated load
restrictions of "Single Unit Truck: 31 tons" and "Combination Truck: 34 tons" on bridge
numbers 030138, 030139, 030140 and 030141 east of S.R. 29 on Immokalee Road.

District 1 Local Government Owned Bridge Inspection Program
Bridge ID: 030138 / CR 846 over Drainage Canal
Dear Mr. Putaansuu :
Upon further review of the of the load rating capacity of this bridge utilizing a refined method of analysis in
accordance with FDOT Load Rating Manual, we concluded that the bridge could be posted at a higher level than
originally noted in the load rating analysis dated January 6, 2012.
We identified the following posting requirement:
• According to the revised load rating analysis dated February 16, 2012 the structure should be posted
at or below the following: Single Unit Truck: 31 Tons, and Combination Truck: 34 Tons. The bridge is
currently not posted. Posting signs should be installed to reflect the latest load rating.
You are hereby notified that it is the County's responsibility to correct the above referenced posting within
thirty (30) days. The Florida Department of Transportation is governed by the Federal Highway Administration
(FHWA) to monitor the corrective action for posting deficiencies. Please notify me in writing of the action taken
and date the correction was completed.
The County's prompt attention to this matter is required as non - compliance could result in the loss of
federal funding. Also, the County shall consider appropriate interim measures to ensure the safety of the public
use of the bridge, pending the installation of the appropriate signage.
Should any questions arise, please contact me.
