CEDAR FALLS COMPREHENSIVE PLAN MAIN TRAVEL LANES


The vision for the study area of University Avenue is a four lane street with a protected left turn lane and a right turn lane at intersections. The right turn lane exits only near intersections, rather than running the entire length of the block, which discourages those trying to pass unsafely on the right. The left turn lane is separated by a median on either side in order to restrict entry/exit to the lane at the intersection, thereby re- ducing potential conflicts. Figure 11.4 shows an example of a road with a protected left turn lane and Figure 11.5 shows a close up of the road design. The design could accommodate a double left turn lane if warranted in high traffic areas, such as in front of the HyVee.

FRONTAGE ROADS The existing frontage roads are too close to University Ave, creating traffic problems be- tween the competing intersections. The concept suggests removing the existing frontage road and improving the existing “backage” roads behind the first row of businesses, to cre- ate a functional backage road connection. Key to the improvement of the backage road system is the creation of controlled access points from adjacent parking lots, as shown in Figure 11.6. This new “backage” road would begin at Tuscon and run east until meeting up with Waterloo Street. It would feature one primary travel lane in each direction and a cen- ter turn lane. Another benefit of removing the existing frontage road system is the expan- sion of space available for enhancement of the corridor and accommodation of pedestrian and bicycle travel, as detailed below.


The frontage road on the north side of University would also be moved back and made into a 3-lane street (Figure 11.7). Because the existing frontage road is necessary to pro- vide access to properties between Valley Park Drive and Royal Drive, the location of the existing frontage road would be maintained for this short block. To resolve the conflict of the Valley Park/Frontage Road intersection, traffic on the frontage way would be one-way eastbound from Valley Park to Royal. One-way traffic would continue north on Royal Drive until meeting up with the new “backage” road. The backage road would then run from Royal Drive to Melrose Drive. In order to enable a straight connection to Melrose, three of the existing storage warehouses between Holiday Road and Melrose Drive would need to be shortened by approximately 1/3 of their current length. The Existing frontage road east of Melrose would be unchanged.


These modifications to the frontage roads would increase traffic safety and provide an eco- nomic benefit by making properties along the backage road more accessible and there- fore more marketable, without reducing access to properties on the existing frontage road.
