Van Milligen, City Manager Gus Psihoyos, City Engineer FROM: Robert Schiesl, Assistant City Engineer DATE: October 14, 2020 SUBJECT: Northwest Arterial - JFK Intersection Right Turn Lane Improvements Acceptance of Public Improvement Contract CIP No. 3002675, lowa DOT Project No. STP-A-2100 (688)-86-31 INTRODUCTION The enclosed resolution provides for the acceptance of the Public Improvement Contract for the Northwest Arterial - JFK Intersection Right Turn Lane Improvements Project. BACKGROUND The northerly approach driving lane of the JFK Road and Northwest Arterial intersection previously had one left turn lane and one shared thru and right turn lane. The thru and right turn movement to go straight or south is a very heavy traffic movement. Previously, it only took one southbound (straight thru) vehicle queued at the light to block all free right turn movements. Once blocked, the shared lane would rapidly back up with vehicles stacking to over 400 feet from the intersection. The City of Dubuque applied for and was awarded an lowa Clean Air Attainment Program (ICAAP) grant from the lowa DOT in the amount of $198,202 to assist with the construction of a right turn lane on the north leg of JFK Road with traffic signal adjustments at NW Arterial and JFK Road intersection. PRE-CONSTRUCTION CONDITIONS Although traffic signal timings at the NW Arterial - JFK intersection are reviewed and updated throughout the year, the prior shared through - right turn lane did not efficiently handle right turning traffic movements. ITS improvements have been implemented at this intersection over the last 10 years to provide the most efficiency from the existing geometrics. This approach had come to the point where no additional efficiencies could be achieved without adding traffic lane improvements. DISCUSSION The JFK Road and NW Arterial intersection turn lane improvement included the construction of a new - exclusive 250-foot right turn lane along the existing northerly approach on JFK Road. The new right turn lane allows for a dedicated straight thru lane as well as maintaining the existing dedicated left turn lane. The turn lane improvement has improved the capacity and efficiency of this intersection. The Northwest Arterial - JFK Intersection Right Turn Lane Improvements Project was completed by Midwest Concrete, Inc. of Peosta, lowa in the final contract amount of $125,886.41 which is a 2.3% decrease from the original contract amount of $128,857.45. RECOMMENDATION I recommend that the City Council accept the improvements and authorize the payment of the contract amount of $125,886.41 to Midwest Concrete, Inc., for the Northwest Arterial - JFK Intersection Right Turn Lane Improvements Project. BUDGETIMPACT The project cost for the turn lane improvements are summarized in the following table: Description Estimate Award Final Construction —JFK New Right Turn Lane $ 140,000.00 $ 128,857.45 $ 125,886.41 Contingency 14,000.00 14,000.00 Engineering Design and Administration 23,100.00 23,100.00 38,100.00 Total Construction Cost Estimate $ 177,100.00 $ 165,957.45 $ 163,986.41 The project funding is summarized as follows: CIP No. Fund Description Fund Amount 3002675 ICAAP Grant (80% construction) $ 100,709.13 3002675 NW Arterial Road Right Turn Lane Improvements 63,277.28 Total Project Funding $ 163,986.41 The grant funding agreement between the lowa DOT and the City provides for the utilization of ICAAP Grant Funds for eligible construction costs for the construction of a new right turn lane.
