Kick Off Event
The community is invited to join us for a kick-off event at 10 a.m. on Tuesday, Feb. 18, 2020 at the corner of North Fifth and Detroit, just alongside the Amtrak Parking lot.
Construction to begin in Feb. 2020.
Ann Arbor railroad north of Depot Street.
Why is this project being done?
This project will lower the floodplain depth at the railroad berm near the mouth of the Allen Creek in the vicinity of Depot and Main Street, just west of the Ann Arbor Amtrak Station. In addition, the project will install a large culvert beneath the railroad that will provide safe and legal access from the downtown area to the Board to Boarder Trail.Work to be done:
Construction of a flood relief opening in the railroad berm that also provides a
new pedestrian path to connect the Depot Street area to the Border-to-Border Trail.
The storm part of the project will consist of the construction of:
two approximately 200 feet by 12 feet by 7 feet hydraulic box culverts with an
outlet to the Huron River, and 286 linear feet of 48-inch pipe storm sewer
improvements to reroute the storm drain in Depot St through the new flood relief
The pedestrian path will go from the corner of Depot Street and
Fifth Avenue , under the railroad tracks in an 85 feet long (14 feet x 12 feet)
tunnel, then on new a bridge over Allen Creek, then connect to the Border-to-Border Trail near Argo Dam.
Possible impact to residents:
The project will have very limited impacts to the public during construction. The majority of work will take place on private property and in the railroad
right-of-way. The railroad will be shutting down for one day in May to
allow for construction. There will be a two week period in June
that the block of Depot Street between Main Street and Forth Avenue will be closed for
storm drain work. A one block detour onto Summit Street will occur during
this time period.
