Four. Construction content

Tohoku Expressway Miyagi Shiraishigawa Bridge, located between the Kunimi IC and Shiraishi IC (upper and lower lines), has been in operation for about 44 years, and due to the increase in size of the vehicle, repeated wheel loads have caused repeated cracks and small cracks. As the concrete floor slab is deteriorated and the reinforcing bars are rusted due to the salt content of the anti-freezing agent spraying, it is necessary to implement drastic measures against deterioration.
By replacing the deteriorated existing concrete slab with a new slab, it will be reborn as Expressway for safe and comfortable use.

6. Efforts to minimize inconvenience to customers due to construction work

[Adopting precast products to shorten the construction period and improve quality]

♦ By adopting a precast PC floor slab, the construction period is shortened and the regulation period is shortened to the maximum.
*Precast is a product manufactured in advance at a factory, etc.

♦ Adopting a precast PC floor slab with waterproof performance
*Conventional on-site waterproofing work is not required, and the construction period is shortened.

[Advance notification of construction regulations and traffic congestion information through TV commercials, radio commercials, newspaper advertisements, etc.]
