Parts of Parker Place, Wall Street and Milwaukee Street are being torn up by AT&T as workers prepare to reroute lines suspended under the Milwaukee Street bridge, a city official said.
The work is being done in advance of the Milwaukee Street bridge replacement project expected to start in October.
The bridge was built in 1913 and once lay in the path of a trolley that took residents throughout downtown Janesville.
The new bridge will be 60 feet wide, seven feet wider than it is now. It will also feature 10-foot-wide sidewalks and could eventually have underside arches.
AT&T’s project to move lines involves opening up pavement in some places and in others will require boring, a more expensive but less invasive technique, said Matt McGarth, senior engineer for the city.
The work started near the AT&T building at the corner of Milwaukee Street and Parker Place.
Boring will involve drilling a hole near Parker Drive. From there, the boring will move under Parker Drive, the cobbled section of Wall Street, Main Street and then the Rock River.
McGarth said the city asked for boring in those sections because Parker Drive and Main Street were recently redone, and the city didn’t want the new pavement dug up.
A large diameter pipe will carry several smaller conduits, McGarth said.
Alliant Energy also plans to move some of its lines that run along the east river wall, McGarth said.
