694 Resurfacing and Ramp Reconstruction
This project will replace the roadway surface with concrete on about six miles of I-694. The new surface should last about 25 to 30 years.

When complete, two lanes of traffic will reopen in each direction, and cable median barrier will extend between opposing lanes.

 

Traffic impacts

• Single lane traffic in each direction will take place for the project’s duration
• Signing for zipper merging during congestion will be used
• Ramps will close, but posted detours will route you around them when they do
• All area businesses will remain and accessible during construction
• This project likely will cause traffic delays, so be sure to check www.511mn.org for real-time traffic conditions. Plan alternate routes if possible.
  
  

Project Description and Purpose
The pavement in the project area has reached the end of its life cycle. This project aims to provide a smoother and safer ride.

The pavement is being rehabilitated with concrete and asphalt. A layer of asphalt is placed atop the original concrete, acting as a flexible separator, and new concrete is placed atop the asphalt. This asphalt layer allows the concrete layers to flex independently of one another, reducing the chance of cracking. This process is lower in cost than removing and replacing existing pavement.

Other features of the project

• Ramp reconstruction at Hwy 61, White Bear Avenue, Century Avenue and Hwy 36
• Minor bridge deck repairs and improvements
• Guardrail replacement
• Culvert replacement
• Slope and grade work
• Construction of four emergency pulloff lanes at I-694 and Hwy 36 as a safety improvement)
