Explanation
Background: This is consent legislation with the Ohio Department of Transportation (ODOT) for a bridge deck overlay project. The work includes a concrete deck overlay on the Broad Street structure over the Scioto River. This work is needed to protect the deck from future deterioration. (FRA-40-12.27 PID 82374)
Since a portion of this project lies within the City of Columbus, this consent ordinance is necessary. Construction of this project is scheduled to begin in the Summer of 2008 and be completed by Fall 2008. This legislation also authorizes the Public Service Director to enter into the necessary agreements to complete this project.
The work will be performed during two weekends while maintaining traffic in one lane in each direction. This work is anticipated to start in late August or early September 2008, and will be coordinated with any festival activity or other projects in the downtown area. The City's Transportation Division will keep ODOT advised of all downtown events and work and will assist with any required coordination.
The overlay is being performed based on the age (17 years) and condition of the existing overlay. The existing overlay is sacrificial with its purpose being to protect the existing deck arch superstructure. Any defects in the overlay could start to directly impact the deck arches.
Recently the City of Columbus performed some patching and reported to ODOT areas where the overlay has become debonded. ODOT determined that it is desirable to do this work now since the Main Street and Town Street bridges may be closed during 2009, and all of the traffic from those bridges will be diverted across the Broad Street Bridge. It is desired to perform this work at this time to preclude the possibility of an overlay failure on the Broad Street Bridge while all downtown traffic is diverted to that structure.
Fiscal Impact: The estimated total cost of this project is $1,860,000. There is no funding requ...
