The causeway will hold the two new roadway lanes. Monday’s work will be off the roadway, but you may notice some construction activity on the south shore of the lake. Crews will be placing rock into the lake to build up the causeway.

Once the causeway is complete, it will need to settle for three to five months. That period ensures that it will be stable enough for crews to begin preparing for the new Guide lanes.

A turbidity curtain is in place to prevent water containing sediment stirred up by construction from seeping into the rest of the lake.
