around the project.
3. Narrative Describing Project Nature and Purpose
A new pedestrian bridge will be constructed over White River to connect the 106th Street trail in Carmel
and Fishers across the river. The new structure will be a 3-span prefabricated steel truss bridge with span
lengths of 150 feet, 200 feet, and 150 feet with reinforced concrete wall piers approximately 4 feet in
width. The structure will have an out-to-out bridge length of 500 feet and an out-to-out coping width of
18 feet. The spill through abutments will have 2:1 sideslopes armored with revetment riprap placed over
a geotextile fabric. The abutments and piers will be skewed 0 degrees to align with streamflow. The
approach trails will meet the existing ground elevations. A temporary construction access crossing will be
placed within the right-of-way on the downstream (west) side of the proposed bridge as well as on the
upstream (east) side of the proposed bridge. It will be completely removed from the floodway upon
completion of the bridge.
Approximately 0.28 miles of approach trail will be constructed to the bridge. The trail contains an asphalt
surface and will be approximately 12 feet wide. Additionally, a new parking lot will be constructed in the
southwest quadrant of the project adjacent to Hazel Dell Parkway.
Cofferdams and dewatering will be required to dry working areas so substructures can be installed in dry
conditions. The approximate location of the coffer dams are shown in Attachment A. Temporary
dewatering measures are expected to be in place less than 4 weeks. The contractor shall verify existing
flowline elevation to set the appropriate pump depth prior to construction and the dewatering hose
positioned so intake does not rest on stream bottom.
This project will be constructed in accordance with the 2022 Indiana Department of Transportation
(INDOT) Standard Specifications, the Indiana Design Manual, and the Indiana Storm Water Quality
Manual. Note that sediment and erosion control measures are subject to change during construction to
meet site conditions. United Consulting shall revise the storm water pollution prevention plan (SWPPP)
as needed to ensure compliance with Indiana Department of Environmental Management Construction
Stormwater General Permit.
