1.0 CIMCITY COMMISSION INFORMATION MEMORANDUM
February 14, 2022
ADMINISTRATIVE BRIEF from Jim Teutsch, Director
Public Works Department
National Bridge Inspection Program:
In 1971, in response to the collapse of the 2,235 foot Silver
Bridge in West Virginia in late 1967 where 46 people lost their
lives, the Federal Highway Administration (FHWA) for the first
time required that all vehicular bridges open to the public that
were built with federal funds or carried a federally funded road
be inspected regularly. In 1978 that requirement was
extended to all public bridges or bridge length culverts that
span a gap of 20' or more. Salina currently has 25 such
structures, the locations of which are shown on the map to the
right. A high profile bridge collapse that occurred in
Minneapolis, Minnesota in 2007 killed 13 people and injured
147 people bringing much-needed attention to the state of
bridges across the country. And just this year on January 28,
a 497 -foot bridge that was owned by the city of Pittsburgh,
Pennsylvania collapsed, injuring 10 people. These examples
highlight the importance of inspecting, maintaining and
repairing our bridges regularly and replacing them as
conditions warrant.
Implementation: The FHWA entrusts the state departments _
of transportation with the implementation of the program, 15 14 t3
which includes maintaining qualifications of bridge inspectors,
ensuring that each of the state's qualifying structures is 16
inspected by its scheduled time, randomly checking each
entity's inspections to ensure their accuracy, and maintaining Salina Structure Locations
a database that is shared with the FHWA annually. The Kansas Department of Transportation (KDOT)
dedicates six full time employees to this program that monitors the more than 20,000 structures in
Kansas.
Inspection:
Until 2013, the City of Salina's structures were inspected by consultant
inspectors. In 2015, City staff completed the requirements to perform
—= -_ - the inspections without consultant assistance. The requirements for a
licensed engineer include: completion of a two week FHWA instructed
class with testing; assisting a qualified inspector with 50 inspections;
attending a KDOT led refresher course each year; and completion of a
three day FHWA instructed refresher class with testing every five years.
s Inspecting a structure, completing the inspection form, and uploading
cy the information into KDOT's database takes three to four staff hours.

Each qualifying structure is inspected every two years until one of its ratings drops to a 3 (more on that
later) at which time its inspection frequency increases to yearly. Structure conditions change very
slowly, thus the FHWA is considering changing the frequency of routine inspections to every four years.
Smaller structures in Salina are also inspected periodically by City staff but their conditions are not
reported to KDOT.
The bridges in West Virginia and Minnesota had members which were considered fracture critical. A
fracture critical member is a steel member the failure of which could cause partial or total collapse of
the bridge. Bridges without fracture critical members are considered to have redundancy, i.e., failure of
one member will be compensated for by another member to protect against a collapse. Salina does not
have any bridges which are considered fracture critical.
Ratings:
A number of different measures are used to quantify the condition of structures.
Culverts carry one overall rating, whereas bridges carry three different ratings:
• Substructure — generally the vertical members of the bridge, like the base of the letter T, usually
comprised of concrete;
Superstructure — generally the horizontal
members of the bridge, like the top of the
letter T, usually either concrete or steel;
Deck — generally the driving surface, usually
concrete.
Structures are rated as follows:
• 9 — new structure not open to traffic;
• 8 — good condition, no repairs needed;
• 7 — generally good condition;
• 6 —fair condition;
• 5 — generally fair condition;
• 4 — poor condition;
• 3 — serious condition;
• 2 — critical condition;
• 1 — imminent failure condition;
• 0 — failed condition, out of service, beyond corrective action
Sufficiency rating is a number from 0 to 100 that indicates the sufficiency of a structure to remain in
service. Generally a sufficiency rating equal to or below 80 indicates a structure is eligible for
rehabilitation and a sufficiency rating equal to or below 50 indicates a structure is eligible for
replacement. State agencies may use sufficiency ratings to prioritize funding. Salina currently has
seven structures eligible for rehabilitation, and the structure on northbound Ninth Street south of 1-70 is
currently being replaced in 2022 at a cost of about $2 million.
Load ratings are completed periodically by licensed structural engineers to determine the load capacity
of structures and often result in the posting of load limits for the structures, which limits the size of
vehicles allowed to cross. Salina currently has four structures posted for load.
The ratings for each of Salina's bridges are listed on the next page.

Summary:
Salina's structures could be described as generally good, with the median rating being a 7 and the full
distribution as follows: 1 — Generally Fair/5; 9 — Fair/6; 13 — Generally Good/7; 1 — Good/8. The north-
bound, Ninth Street bridge over Mulberry Creek currently being replaced will soon be added to the
Good/8 category.
Salina's investment in structures that are still in use by decade is: 1940's, 2; 1950's, 7; 1960's, 5;
1970's, 0; 1980's, 1; 1990's, 3; 2000's, 5; 2010's, 1; and 2020's, 1 for an average of about three per
decade. As such, while none of Salina's bridges is even in serious condition, it is logical to expect that
further structure expenses beyond this year's replacement will likely be incurred in the 2020's.
While not a bridge length culvert (and therefore not part of this inventory), a 4' tall and 10' wide, 1970s
box culvert located under Winn Road south of Northwood Lane was recently closed due to
delamination of interior concrete and the loss of structural integrity. Though not a requirement as part of
this bridge inventory, Public Works staff will inspect and report on the condition of all such culverts in
Salina in 2022.
