Indian River Bridge - Roadway Approach & Existing Bridge Demolition
Frequently Asked Questions
How will motorists be impacted as the approaches are being built?
From mid May 2011 through early 2012, a new traffic pattern will be in place at the approaches to the Indian River Inlet area.
Both Route 1 northbound and southbound traffic will be reduced to one lane in each direction, with the reduced speed limit of 35 mph remaining in effect. This traffic configuration will be in place on the Route 1 northbound lanes.
How will cyclists and pedestrians be impacted as the approaches are built?
During Phase I (March-May 2011) cyclists and pedestrians will continue utilizing the current configurations in place. During Phase II, cyclists will utilize the shoulder area and be on alignment with motorists until they reach the existing bridge structure. While on the existing bridge they will be separated by a concrete barrier and will utilize the SR-1 southbound lanes exclusively until they reach a point just over the existing bridge structure when they will return to the shoulder area and once again be on alignment with motorists. Pedestrians will continue to use the existing detour. During Phase III, cyclists will be in the shoulder area, but on the same alignment as motorists. Pedestrians will continue to use the existing detour.
How will the old bridge be demolished and what will happen to it after it is dismantled/demolished?
The contractor will determine how the bridge will be disposed, however it will not be imploded or exploded due to marine life and proximity to the occupied roadway. It is anticipated that all concrete barriers, piers and decking will be removed using jackhammers and heavy equipment and be transported to a reef site. Steel from the bridge will either be placed at the reef site or recycled, whichever provides the best economic benefit.
Why didn't Skanska, the new IRIB bridge contractor, build the approaches first as the original bridge design was intended?
Skanska, the bridge builder, was contracted to only build the new bridge, not the approaches. Their design allowed for the Roadway Approach contract to be bid and built separately, which allowed for a faster bid process and a more aggressive construction schedule of the bridge structure itself.
What will the traffic pattern be on Memorial Day Weekend and throughout summer 2011 and into 2012?
The traffic pattern will be established prior to Memorial Day Weekend and will remain throughout the remainder of 2011 and into early 2012. Motorists can expect one lane available in each direction over the existing Indian River Inlet Bridge. This traffic configuration will be in place on the Route 1 northbound lanes.
Is this project a design-build like the new IRIB or is it a traditional bid build contract?
The Roadway Approach contract is a traditional bid project. It was designed in coordination with the new Indian River Inlet Bridge, but is a totally separate contract with a different contractor.
What type of coordination must occur between DelDOT, Skanska and the Roadway Approach Contractor?
Regular meetings, including project progress meetings and public Construction Advisory Group meetings will allow for close coordination between the two projects. Extensive coordination and communication will occur between George & Lynch (the Roadway Approach contractor) and Skanska (the bridge contractor) over the next year and a half.
What other work is occurring in this area and when?
Following the construction of the bridge approaches and existing bridge demolition, park improvements will occur in 2012 and 2013. Click on those links for more information.
