Q: How many bridges are being built?
A: Two. The first new bridge is now open to traffic and was built to the north of the 1950's-era bridge. This first new bridge will carry westbound traffic when both bridges are complete. A separate contract has been issued to build the second new bridge. The 1950's era bridge will be removed and a second new bridge will be built to carry eastbound traffic.
Q: Why is ODOT building two new bridges?
A: By constructing two bridges, ODOT is able to maintain traffic on I-90 – a vital link into Downtown Cleveland. During construction of the second new bridge, the first bridge will be used to maintain traffic while the eastbound bridge is constructed.
Q: How many lanes will each bridge have when complete?
A: Each new bridge will carry five lanes of traffic when complete - one more than the 1950's-era bridge carried.
Q: Each new bridge is being constructed using the "design-build" method. What is “design-build?”
A: In order to complete construction of the new bridges faster, ODOT is using a unique value based "design-build" process, in which the design and construction of the projects are performed by a team of designers and construction contractors. In a typical "design-bid-build" project, design is completed prior to bidding and a project of this magnitude could take a number of years to be designed, let alone constructed. The overlapping of design and construction also reduces the likelihood of project delays, as construction work is on-going.
Q: How long and tall are the new bridges?
A: The new westbound bridge is about 4,347 feet long. The eastbound bridge will be about 3,918 feet long. Both bridges will stand about 115 feet over the CSX railroad on the eastern end (10 feet lower than its predecessor) and 136 feet over the Cuyahoga River.
Q: Will the two, new bridges look similar?
A: Yes, the two bridges will be "sister" bridges and will have the same "delta girder" shape.
Q: What happens to the 1950's-era bridge?
A: Demolition of the 1950's-era bridge began in January 2014. The team is using a mixture of both traditional demolition and “controlled” – or explosive – demolition. Controlled demolition is currently scheduled to take place during the summer of 2014. The bridge is expected to be demolished in its entirety by summer 2014. Nearly all of the materials from the demolished bridge will be reused or recycled.
Q: How is traffic maintained during construction?
A: The new westbound bridge is temporarily carrying traffic in both directions – two, thru lanes in each direction as well as dedicated access to I-90 west from both E 9th and Ontario Streets – during construction of the second new bridge. Some entrance and exit ramps are closed. An additional lane of traffic has been added to I-490 and I-77 to carry the influx of traffic from motorists who wish to avoid the construction zone.
Q: How many vehicles use this stretch of I-90 each day?
A: About 140,000 vehicles use this stretch of I-90 every day.
