2022-09-06 P&E Agenda - Item 5 - Attachment 1 - Six Mile Creek Bridge Replacement Offset Report - TMR

Figure 1.4 Constructability diagrams indicating how bridge construction will avoid impacts to the existing Six
           Mile Creek channel


In summary, the proposed action includes:
   New 4 span concrete bridge to be constructed approximately 15 m west (downstream) of the existing
    bridge structure
   Cast in place concrete piles
   No disturbance to the existing Six Mile Creek channel (i.e. construction and piling outside of existing
    creek system under normal hydrological flows, as the bridge will span the channel)
   Material from the existing timber bridge structure to be utilised by TMR for maintenance of other timber
    bridges within the network, with footings within Six Mile Creek remaining in situ to maintain current fish
    habitat values
   Existing road to be widened in the approach to the new bridge (will not result in additional fragmentation
    of surrounding landscape).
The proposed action is planned to be constructed in 2022 and is expected to take between 6 to 9 months to
construct and complete with 4 months working around the creek.
