An $8.3 million project is in full swing to replace the nearly 70-year-old Beaver Island Parkway Bridge over the I-190 section of the Thruway. Since late March, crews and heavy equipment have been tearing down the old and making way for the new, while motorists who previously took Beaver Island Exit 18B have had to follow a detour to get home, to work or to businesses on the Island since April 3.
