·         Grading and concrete pavement installation along O'Keeffe Avenue

Traffic control:

·         Traffic control will remain the same all of next week.

Truck Traffic Advisory: 

·         It is currently very difficult for large trucks to make a left turn onto Main Street from the SB 151 ramp. These trucks may want to either 1) turn right and go around the Round-a-bout to go east bound on Main Street, or 2) they could go up to the 151-CTH C - Reiner Rd interchange and turn around to head NB on 151and exit on to Main Street. This right turn is much easier for large trucks.

Traffic control will remain the same for this week.  Note that there are no turns onto Main Street from O'Keeffe Ave.

Persons travelling this route are advised that construction is likely to be occurring on Saturdays for the next several weeks.  People are also strongly encouraged to continue to slow down and watch for construction workers and equipment at all times in the construction zone.   

In addition, vehicles traveling westbound on W. Main Street. and wanting to access businesses along O'Keeffe Avenue must turn at the Clarmar Drive intersection.  Access to O'Keeffe Avenue for westbound vehicles does not exist west of Clarmar Drive.  The contractor has reported multiple occasions where westbound vehicles on Main St. have tried to turn left on to the 151 off-ramp to Main St.  Drivers are asked to be mindful of where allowable access routes are located.

The next business meeting is scheduled for October 6th at 9:00 a.m.
