Cross Section at 16 Mile Creek Bridge
Enquiry
According to the Design Criteria (Table C-1, Document #4), the cross-section drawing of Sixteen Mile Creek Bridge (Proposed) on page 11 of 12 shows that the width of the median shoulders on both Westbound (WB) and Eastbound (EB) structures is 3.26 m, and the distance between the shoulders is 0.98 m. The gap between the WB and EB structures is 30mm, and the deck is aligned across the gap. This is consistent with the RFP, Section 2.4.8.2, item (j) under the Sixteen Mile Creek structure design requirements, under which the median shoulder width is 3.26 m, the barrier wall width is 0.475 m and the gap between the structures is 0.03 m. (0.475 m*2 + 0.03 m= 0.98 m) However, on the Structural Design Report for Sixteen Mile Creek Overpass (Table C-1, Document #9-3), Section 4.2 (cross-section for Highway 401 at the Sixteen Mile Creek Bridge) states that the median shoulder width is 3.075 m, the barrier wall width is 0.525 m and the gap between the structures is 300mm. The cross-section for Highway 401 at the Sixteen Mile Creek Bridge in the General Arrangement Drawings (Table C-1, Document #7) is consistent with the SDR, and shows that the median shoulder width is 3.075 m and the distance between the shoulders is 1.35 m. The gap between the WB and EB structures is 300 mm, and the deck is NOT aligned across the gap. Please confirm the correct median shoulder width, barrier wall width, gap width between WB and EB structures on the 16 Mile Creek Bridge, and if the deck should be aligned across the gap.
