Project Built-Upon Area (ac.)
The existing 90'8', 3 span bridge over Long Creek on SR 1134 (Millingport Road) is being replaced with a 2 span bridge with a span arrangement of 1@70' (24" cored slab),
1@50' (21" cored slab). The bridge will have 1.5:1 sloping abutments. The bridge will be super elevated to the left at 4% with 10' travel lanes and 3'11" to the left and right
shoulders, 27'10" clear width and 30' OTO width. The existing bridge structure will be removed. Overall drainage patterns will be maintained. There are proposed ditches that flow
towards the stream on both the begin and end sides on the downstream portion of the bridge and on the end side of the upstream portion of the bridge. On the begin side of the
bridge, a traffic bearing grated drop inlet with double frame and grates (2GI) is placed on the left side of the roadway in the shoulder berm gutter to pick up runoff from the bridge.
Class-II riprap abutment protection on both banks of the stream is also proposed to prevent future erosion and stream migration. Deck drains are not required. Impervious dikes
will be used around existing abutments to prevent the sediment from entering the stream during the removal of the existing bridge and will be dewatered as needed. A water line
will be constructed that will require the use of impervious dikes and a temporary 48" pipe will be used to divert the stream.
