BRIDGE REPORT Date of Investigation .7 ,000 ........000E...Year 1972 RATING OF CONDITION: Deck Substructure 6 Superstructure Overall 5 PLANS The plans for the original structure and those for the 1924 widening are not available. The plans for the 1928 widening were prepared by the State Division of Highways, and are entitled "Widening of Bridge Across Las Encinas Creek." . Plans for repairs made to thistructhe in 1959 are entitled "Repair 3 Bridges Across Los Penasquitos Creek, .San Marcos Creek and Los Encinas Creek." The structural details of. the original structure and the initial widening are not shown on thewidening or repair plans. The 1913 and 1924 structure has. concrete T-beams normal to the abutments. The 1928 widening added 3 concrete T-beams on the left and 4 on the •right side parallel to the roadway. The 1928 widening also added 1 girder on the right side normal to the abutments adjacent to the original structure. Bays 3 and 8 vary in width due to the skew. PREVIOUS REPORTS Bridge Report of July 28, 1937 by R. A. Wagner, and supple- ments thru 1966. Supplementary Bridge Report of March 27, 1967 states that the Bridge was relinquished to .the City of Carlsbad. It was formerly numbered 57-l2L. HISTORY This structure formerly carried two directions of highway traffic. In 1951 the State constructed a box culvert FORM HBD.M70A , Bmi'€ No. .1cL214Z. S: ( structure upstream to carry the northbound traffic. Route FAX 5 now carries the highway traffic, and this structure receives local and beach traffic. I The Bridge has had a history of reinforcement corrosion and resultant concrete cracking and spalling. The concrete girders and deck soffit have been repaired with gunite in 1938, 1956, and 1959. In 1964 both rails were replaced. CONDITION OF STRUCTURE The concrete railing end posts are cracked and spalled with reinforcement exposed. There is approximately 5 inches of AC surfacing on the deck. It is uncracked. The construction joint at the base of the rail on the ex- terior sides is open. Much of the deck soffit of the original structure has a gunite coating. This repair appears effective. Many of the girders have been repaired with gunite. Girder 1 (from the left — ocean side) has shrinkage cracks in the gunite. It is cracked horizontally 6 inches from the bottom with vertical cracks in the middle:third. The soffit of the girder is also cracked longitudinally. Girder 3 has a horizontal crack 3 inches from the bottom. Girder 7 is cracked horizontally at the bottom reinforcement layer 1/4 inch in width. The cover has spalled off the bottom over a large area. The exposed reinforcement.is badly corroded. There were no visible problems in the other girders. CHANNEL The channel on the upstream side is unlined. On the down- stream (left) side of the structure is the ocean beach. CAPACITY This structure is considered safe for legal loads at this time. The bridge will require continued inspection, as the corro- sion will progress at an accelerating rate. Calculations indicate that the structure can carry no over- loads. FORM H-BD M 18 ST. 4717. 32401.500 5.63 2M COP PENO.:2214L__ DATE47 ._ POSTING RECOMMENDATION • Legal Loads • Only W. R.
