Other construction activities scheduled for the week of June 23 include: 

• Continuing to paint Span 1 on the south side of the river (see the before and after views in the photo above) and beginning to paint Span 3 on the north side.
• Setting up a concrete batch plant and preparing to pave sections of the I-35W roadway north of the river.
• Installing fencing along the highway from University Avenue to Fourth Street Southeast.
• Installing foundations for lighting and signs near the entrance and exit ramps at University Avenue and Washington Avenue.
• Pouring the northbound lanes of Span 4, which will bridge the gap between Pier 4 and Abutment 5 on the north side.

The aerial photo below shows, from top to bottom, Span 1 on the south bank of the Mississippi, the narrowing gap over the river where the main span is being constructed, Span 3, the northbound lanes of Span 4, a section of highway yet to be paved, the partially paved Second Street Bridge, and more unpaved highway, including the exit ramp to University Avenue on the left.

Potential Noise Impacts 

• The concrete crushing machine that was previously used on the north side of the project is now set up at Abutment 1 on the south side. As crews complete the demolition of the old road bed on I-35W, the crusher will break the large chunks of concrete into gravel that can be used for the base of the new roadway. The concrete crusher will operate between 7 a.m. and 9 p.m. until the end of the week.
• As night-time paving begins on the north side of the project, backup alarms may be increasingly noticeable in that area.
• Following paving, crews will need to make cuts in the concrete to prevent cracking. Sawing the expansion joints will create noise intermittently during day and night shifts. 

Potential Traffic Impacts

As the project progresses, residents and commuters may encounter activities that will affect traffic in the area. In particular: 

• Crews will periodically close 13th Avenue South from the casting yard entrance to West River Parkway as they transport pre-cast segments to the river. Hauling operations will take place between 7 a.m. and 7 p.m. intermittently until the end of June. The road will close for up to 10 minutes each time a segment is moved. 
• Construction traffic will continue in the vicinity of the site. Some of the streets affected include Second Street Southeast (between 11th Avenue Southeast and Sixth Avenue Southeast), First Street South and 19th Avenue South, Bluff Street south to 13th Avenue South, and Second Street South (between 13th Avenue South and 11th Avenue South).

Potential Light Impacts

Crews are working night shifts seven days a week on both sides of the river. Lights and construction traffic may be noticeable between 5:30 p.m. and 4 a.m.
