NEW Eastbound K-10 to Northbound I-435 Flyover Ramp
OPENING TOMORROW! The NEW eastbound K-10 to northbound I-435 two-lane flyover ramp will OPEN to all traffic by Thursday evening, July 30, weather permitting. Once the new ramp is fully opened to all traffic, the existing eastbound K-10 to northbound I-435 single lane flyover ramp will be PERMANENTLY CLOSED to all traffic and demolition work of the existing structure will begin on Monday evening, August 3.
The existing eastbound K-10 to northbound I-435 flyover ramp bridge will be demolished by heavy equipment via a series of overnight full roadway closures on I-435 and/or K-10. There will be no implosions for the bridge removal. Demolition work on the existing flyover ramp bridge will take place overnight beginning at 10 p.m. and reopening to all traffic at 5 a.m. p.m. the following morning, daily Monday, August 3-Wednesday, August 12, (excluding overnight closures on Friday-Sunday, August 7-9), weather permitting. The overnight closures are needed so that crews can safely remove the flyover bridge ramp structure. Advance separate notification will be sent for next week’s overnight full roadway closures.
The process for the flyover bridge ramp demolition and removal will occur as follows (see flyover bridge diagram below). Plywood will be placed on existing K-10 and I-435 roadway to protect pavement from any impact damage from falling debris.
1) Barrier wall/handrails and the bridge deck will be removed will be removed via excavator. The excavators have heavy hammer attachments that will “peck away” at the structures.
2) Structural steel bridge girders (which support the bridge deck) will be cut and removed in sections via crane off the bridge piers and abutments.
3) Bridge piers and abutments (which support the bridge girders) will be removed via excavator. The excavators have heavy hammer attachments that will “peck away” at the structures.
