What to expect

Paving:  
What to expect

What: Resurfacing existing roadways -- not new construction of a road. Kinda like painting your kitchen -- not remodelling it.
When
: June, July, August. Materials and processes work best in summer.
Where: Segments of Waukesha County Highways all over the county.
How long: Most take three or four days. But weather, length of segment may add a few days.
Safety First: Please expect lane closures. That means flaggers on site -- so please stay alert and decrease speeds. We appreciate it! 

More info: Your questions and comments are welcome! Contact Nate Beth of DPW-Engineering Services (email)

Before you contact us: Encountering rough road where we've started paving? Hang tight -- it's not done yet! A week or two may pass between the "base patching" and "milling / paving" phases. Thank you! 

More projects: We aren't the only team at work on roads in beautiful Waukesha County. Check out "Who Maintains My Road?" for more info.

We apologize for any inconvenience. Thank you!
