Remote overnight concrete curing for bridge elements

The bridge opened to traffic in 1955 and was at that time designed for a humongous number of 100.00 vehicles per day. In the past decades, daily bridge traffic has grown to about 138,000 vehicles.

Heavy traffic and lack of emergency shoulders can create unsafe driving conditions on the bridge and lead to frequent congestion and frustration for motorists.
