IR 470 Ramps at SR 7

3. Existing Conditions

The interchange is a trumpet interchange, with a loop ramp in the northwest quadrant. SR 7 runs north and south while IR 470 runs east and west. The ramps create a three leg, stop controlled intersection.

To the west of the interchange, IR 470 is a divided highway with two lanes in the eastbound direction and three in the westbound direction. Immediately to the east of the interchange, IR 470 is a divided highway with two lanes in each direction. The IR 470 exit ramp is two lanes, while the entrance ramp is one lane. The westbound entrance ramp connects to IR 470 as an add lane. IR 470 and the ramps are constructed of asphalt over a concrete base.

Within the project area, SR 7 is a four-lane divided asphalt concrete roadway. The northbound and southbound entrance and exit ramps for SR 7 are single lane. SR 7 northbound and southbound exit ramps are asphalt over concrete base.

4. Problem Description

This study follows the “BEL-07-18.19 Safety Study” which evaluated the existing safety performance and identified potential improvements to the interchange in order to reduce congestion and crashes at the interchange of IR 470 and SR 7. There were a total of 29 crashes within the study area over a three year period between 2011 and 2013. Of these 29 crashes, 22 were rear end crashes.



The most significant congestion problems at the interchange occur at the northbound and eastbound approaches at the intersection. During peak hours the SR 7 northbound exit ramp queue extends back to the mainline of SR 7, and the IR 470 eastbound exit queue extends back to the merge point of the eastbound and westbound ramps. These extended queues contribute to the high number of rear end crashes. Congestion issues exist due to the insufficient storage and capacity of these approaches and the intersection being stopped controlled. The increased traffic volumes for the design year will further increase the congestion and potential for crashes.

The purpose of this study is to identify modifications to the interchange which will improve the traffic flow and reduce congestion without impacting operations on IR 470 or SR 7.

5.4 No Build Intersection

Figure 4 SR 7 & IR 470 Westbound Exit Ramp No Build Condition

The existing SR 7 exit ramps, both northbound and southbound have one sixteen foot lane with a four foot outside shoulder and a three foot inside shoulder. The pavement is asphalt over concrete base and all the ramps at the intersection are stop controlled.

The westbound IR 470 exit ramp is two lanes at the intersection. The lanes are approximately twelve feet in width with adequate shoulders. The IR 470 eastbound entrance ramp has one lane approximately sixteen feet wide, with adequate shoulders. The pavement of both ramps is asphalt over concrete base. The entrance and exit ramps are separated by a concrete barrier.



5.5 Build Intersection

Figure 5 SR 7 & IR 470 Westbound Exit Ramp Build Condition

The proposed build condition constructs a new 425 foot left turn lane for the northbound SR 7 ramp. Each lane is twelve feet in width with a six foot outside shoulder and a three foot inside shoulder. The outside lane is protected with guardrail due to the steeper slopes required to provide wider ditches to meet best management practices. The southbound SR 7 ramp pavement is widened to install a concrete traffic island to restrict thru movements.

IR 470 entrance ramp is widened to two lanes, providing a dedicated lane to each westbound and eastbound ramps. The center concrete median will be removed as needed to allow the dual left turns from the northbound SR 7 ramp.

A traffic signal will be installed with stop line and dilemma zone detection to replace the existing stop controlled operation.



6. Conclusion

The proposed design of the intersection will improve the issues of safety and congestion. The addition of a second northbound turn lane, the restriction southbound and northbound thru traffic, and the installation of a traffic signal will increase the capacity and storage for the intersection. The improvements will reduce the queues lengths on the northbound and eastbound approaches and provide better operational characteristics of the intersection. With the intersection functioning more efficiently, the crashes caused by congestion could potentially be mitigated. Neither IR 470 nor SR 7 will be adversely affected by the proposed improvements.
