The Connecticut Department of Transportation says it will begin a $30 million rehabilitation project on the 54-year-old Putnam Bridge April 1.
Spokesman Kevin Nursick says in order to have the smallest impact on commuters travelling between Wethersfield and Glastonbury, the bridge will be open to two lanes of travel in each direction during rush hour, and restricted to a single lane at night.
He says the project has multiple components, but will focus mainly on repairs and replacement of structural steel, including replacement of all expansion joints and bridge bearings. The median and parapets on each side of the bridge will be replaced and the concrete substructure will be repaired
A deck replacement project on the bridge was completed in 2008. The new work is expected to take into 2015.
