Huge 12 foot tall steel wheels called trunions have arrived for the September Interstate Bridge project.
The trunion at the top of the northbound span needs to be replaced.
Starting September 12 through September 20 the northbound span will be closed for the work.
All traffic will be diverted to the southbound span. It'll have alternating lanes to accommodate morning and afternoon commute traffic flows.
In the morning, there will be two southbound lanes and one northbound lane. In the afternoon, there will be two northbound lanes and one southbound lane.
Long delays are expected. Drivers are advised to use I-205.
