Location:	6.3 MI. E. JCT. SR1229
Purpose:	Carries highway over waterway
Route classification:	Principal Arterial - Other (Rural) `[02]`
Length of largest span:	130.9 ft. `[39.9 m]`
Total length:	14961.7 ft. `[4560.1 m]`
Roadway width between curbs:	25.9 ft. `[7.9 m]`
Deck width edge-to-edge:	31.8 ft. `[9.7 m]`
Vertical clearance below bridge:	13.1 ft. `[4.0 m]`
Owner:	State Highway Agency `[01]`
Year built:	1960
Historic significance:	Bridge is not eligible for the National Register of Historic Places `[5]`
Design load:	M 9 / H 10 `[1]`
Number of main spans:	2
Main spans material:	Steel `[3]`
Main spans design:	Movable - Swing `[17]`
Deck type:	Closed Grating `[4]`
Wearing surface:	Monolithic Concrete (concurrently placed with structural deck) `[1]`

Good/Fair/Poor Condition:	Poor
Status:	Open, no restriction `[A]`
Average daily traffic:	3,600 `[as of 2015]`
Truck traffic:	14% of total traffic
Deck condition:	Fair `[5 out of 9]`
Superstructure condition:	Fair `[5 out of 9]`
Substructure condition:	Poor `[4 out of 9]`
Structural appraisal:	Meets minimum tolerable limits to be left in place as is `[4]`
Deck geometry appraisal:	Basically intolerable requiring high priority of corrrective action `[3]`
Water adequacy appraisal:	Better than present minimum criteria `[7]`
Roadway alignment appraisal:	Equal to present desirable criteria `[8]`
Channel protection:	Bank protection is being eroded. River control devices and/or embankment have major damage. Trees and rush restrict the channel. `[5]`
Pier/abutment protection:	In place and functioning `[2]`
Scour condition:	Bridge foundations determined to be stable for the assessed or calculated scour condition. `[8]`
Sufficiency rating:	32.0
Recommended work:	Replacement of bridge or other structure because of substandard load carrying capacity or substantial bridge roadway geometry. `[31]`
