� . . . . <br /> joint is spalling and leaking. A large void down- <br /> stream extends under the end of the box sewer (photos <br /> 2 & 3, MH C-5 to MH C-4) . <br /> 6. �o�± brick tranaition section with aoncrete patahinq: <br /> Mortar is deteriorated and patch work spalling. <br /> 7. �15 LF ot l8�� RCP to Franklin 8treet: Continuous <br /> hairline cracks are visible along the pipe crown and <br /> most joints are leaking and developing leak deposits. <br /> The pipe is considered structurally sound. <br /> 8. 70 LF of 5� brick arch with flat brf ck invert (under <br /> Jackson Street) : There is a large concrete build up <br /> at the junction of walls and base at the start of <br /> this section, probable patchwork. Loose and missing <br /> brick extend throughout, with extensive mortar loss. <br /> Large quantities of brick and debris are scattered <br /> along the invert. Structural stabflity of this <br /> section is questionable although it lies under a <br /> major highway. <br /> 9 . 225 LF of 48�� RCP: Condition is about same as 7. <br /> above. Deterioration of concrete has exposed rein- <br /> forcing for a distance of 25 '± in the lower portion <br /> of this section. <br /> 10. 25 LF of 54�� CMP arch with concrete invert: The <br /> invert and bottom are in good condition. Exposed CMP <br /> is heavily rusted. Small voids appear at each end <br /> of the section. <br /> 87023A 8-13 <br /> 22 of 29 <br />
