    Project Scope 

    The project will make improvements to the Wadsworth Boulevard and Waterton Road intersection. These improvements will greatly improve safety of the intersection. In addition, a portion of Waterton Road will be widened. Improvements include, but are not limited to: a new mast arm traffic signal, new raised concrete medians, new dedicated turn lanes, addition of bicycle lanes, construction of a new concrete box culvert bridge at Brush Creek, and significant drainage improvements.

    The project has been awarded to SEMA Construction, Inc. for a Contract amount of $4,096,491.20.  The project is funded by Jefferson County as well as CDOT Funding Advancements for Surface Transportation and Economy Recovery (FASTER) Act of 2009 funds. Construction is anticipated to be complete in June 2017.

    Project Update (as of April 25, 2017)

    Starting on Thursday, April 27, the new traffic signal at the Wadsworth Boulevard and Waterton Road intersection will be activated in flash mode. Wadsworth Boulevard will flash yellow and Waterton Road will flash red 24 hours per day for several days to alert drivers that a new traffic signal is being placed into service. The current traffic pattern will remain in place until the signal is fully operational on Tuesday, May 2.

    All Waterton Road traffic entering the intersection must continue to turn right while the signal is in flash mode. With wet weather in the forecast, this schedule is subject to change.

    Motorists will notice an increase in truck traffic this week as the last section of Waterton Road is paved. Paving is scheduled for Friday, April 28. Final roadway striping is scheduled for Monday, May 1 and Tuesday, May 2 in advance of full signal activation.

    Once the signal is fully operational, Waterton Road traffic headed to Lockheed Martin will use the dedicated left turn lanes at the intersection to enter the plant instead of the median turn-around that has been in place for several months.

    The work zone speed limit is 25 mph and strictly enforced.
