Now, the new center bridge allows for all four lanes of I to be maintained in each direction while repairs are made to the existing bridges. After repairs to the existing structures are made and the existing concrete decks are replaced, the new center bridge will provide two additional permanent lanes on I in each direction.
In addition to the significant bridge design work, the project includes design of reconstructed bridge approach roadways on I to connect the new bridge to the existing highway system, drainage design along I as well in the Cuyahoga River Valley below, traffic control, lighting and ITS elements.
The new center bridge is 4, feet long and rises up to nearly feet above the Cuyahoga River Valley below. Situated in the median gap between the existing eastbound and westbound bridges, extensive engineering analysis was required to facilitate erecting the new bridge with gantry cranes spanning between the existing structures. Although pile setup is widely acknowledged and known to provide significant increase of vertical resistance capacity of driven piles over time, the current bridge design specifications do not provide design procedures for quantifying increased usable resistance capacity of driven piles due to setup.
By installing test piles at the site of each foundation and then measuring the capacity strength gain of those piles over a period of weeks, Jacobs developed a rate of strength gain curve for each driven pile foundation. Ultimately, we were able to quantify significantly higher pile resistance capacities of the center bridge foundation piles compared to the traditional approach of determining usable pile capacity based primarily on end-of-drive criteria.
This reduced the total number and length of piles required to support the center bridge foundation loads. Doing so saved significant construction cost due to reduced pile quantities, and also saved significant time during installation. All rights reserved About Us.
