BIENNIAL BRIDGE INSPECTION SUMMARY
N. GRAND RIVER AVE. OVER THE GRAND RIVER
STRUCTURE NUMBER – 3947
CITY OF LANSING, MI
October 10, 2017
The bridge consists of three closed spandrel, earth filled,
reinforced concrete arches with two concrete pier walls in the
water. The bridge was constructed in 1924, and the sidewalks and railings replaced in 1979. The bridge overall is
in fair condition.
DECK
The road wearing surface is in poor condition, though it is not actually part of the superstructure. The concrete
wearing surface has several open longitudinal and transverse cracks, including block cracking along the
longitudinal construction joint. There are several bituminous patches, many failing.
SUPERSTRUCTURE
The reinforced concrete arches are in fair condition. Longitudinal construction joints at third points in all three
spans. Mostly minor leaching with occasional spots of efflorescence and/or rust along construction joints.
Heaving leaking with mineral build-up at bottom of construction joints just above pier wall support. Longitudinal
cracks within 2-foot (ft) to 4-ft in from fascias near crown of arches. Some of these cracks with efflorescence and
rust. Wider, longer crack near east fascia of south span and west face of center span. Some transverse cracks
near crown points as well. Few shallow steel spalls in south span. Sporadic cracks with leaching and some
efflorescence in headwalls. Leaching with some efflorescence along horizontal joint between deck fascia and
headwalls. Vertical spalls along headwall/pilaster joint extending above pier walls. Spall with heavy cracking,
rust, efflorescence and leaking between headwall and return wall in northwest. Spalls on arch fascias near
crown: Span 1S east fascia 6-square foot (sft); Span 2S east fascia 8-sft; Span 3S west fascia 6-sft.
SUBSTRUCTURE
The pier walls are in fair condition. We found heavy leaching along construction joints with arches, and heavy
leaking from longitudinal construction joints in arches just above piers. Pier wall nosing has several leaching
cracks at all four locations. There are two spalls in the north face of south pier totaling 25-sft. There are a few
vertical cracks with leaching in each wall. Shallow spalls are forming under weep holes and longitudinal joint
leakage. These spalls are forming through what appears to be a thin concrete skim coat.
APPROACHES
The hot mix asphalt (HMA) approach pavements are in poor condition. We found several wide open longitudinal
and transverse cracks and block cracking in each, with settlement bumps at the reference lines. There are
several bituminous patches, many failing, particularly at the reference lines.
RECOMMENDATIONS:
• Replace deck with new sidewalks, railings and wearing surface.
• Replace approach pavements.
• Patch spalls in headwalls.
• Epoxy inject longitudinal joints near pier walls and larger cracks in arches.
• Add riprap in front of abutments.
• Provide advance load posting signs.
