Weekdays from 7 a.m. to 5:30 p.m. through late August, the westbound lane of East First Street will be closed between Main and Flume streets, as will adjacent street parking.
The southbound lane of Wall Street will also be closed for one block between East First and East Second streets, along with adjacent parking. Sidewalks may also be closed at certain times.
PG&E is moving underground equipment to make way for the city of Chico's "couplet project," which includes a roundabout at East First, East Second, and Flume streets.
Upgrades will meet future electrical needs.
Once work is completed each day, streets will reopen to traffic along with most parking.
