Show Highway 41 Corridor Master Plan____________ April 2002 The improvements are proposed to accommodate the growth in traffic that is likely to occur as the result of the land use alternatives; although, it should be noted that the Prairie Preservation Plan alternative would be similar to a "no/reduced-build" condition. Capacity improvements would still be required with this alternative, due to the normal increase of traffic on Highway 41 and because of the development growth that will occur within the Cities of Post Falls and Rathdrum, regardless of the implementation of this plan. The improvements are the result of preliminary forecast analyses of future capacity restraints and Project Team discussions concerning local and regional needs. Not all of the proposed improvements would be the function of this plan, as there are projects that are likely to occur separately, or in conjunction, with other planning/improvement efforts such as those that will occur with the US 95 project. Figure 14 provides a summary of improvements for the proposed Highway 41 corridor and adjacent primary roadways and can be used in conjunction with the following discussion of improvements. State Highway 41 State Highway 41 is currendy a two- to four-lane roadway with generally 100-foot ROW (ROW) between Seltice Way and Poleline Avenue. North of Poleline Avenue, the highway reduces to two lanes with varying ROW to the City of Rathdrum. Left turn lanes are provided at both Prairie and Hayden Avenues. This Plan proposes to improve Highway 41 to four lanes from Seltice Way to Rathdrum with a 130 to 200-foot ROW. The newly constructed section would have 12-foot-wide lanes with a 16-foot median restriction that will only allow left turns at principal roadways and selected Wmile access locations (at Hope and 16th Avenues). Left turns from Highway 41 would also be allowed at 12th and Horsehaven/20th Avenues, but not from the local cross streets. Right turns will be allowed at east/west access roads along the highway. Improvements would also include 10-foot swales for stormwater runoff and a 10-foot paved bicycle/pedestrian pathway on both sides of the roadway. Traffic Signals Traffic signals are currently located on Highway 41 at Seltice Way, the westbound 1-90 ramp, and Mullan, Poleline, Prairie, and Hayden Avenues. Traffic signals are proposed at 16th, Hope, Wyoming, and Lancaster Avenues. The signals would allow for protected/exclusive -. left turns, which means that designated left turn lanes would be provided/constructed on all intersection approaches. Designated right turn lanes would be provided at arterial intersections on both Highway 41 and the cross collector/arterial streets. Road Widening Projects Both approaches to Highway 41 on Lancaster (possible future 5-lane), Wyoming, Hope, Poleline (east-leg only), and 16th Avenues would be widened to three lanes from the Highway 41 intersection to the proposed north/ south V^-mile access road. Both approaches to Highway 41 on Hayden Avenue (from the intersection for % mile), Prairie - Avenue, Poleline Avenue (west leg only), and Mullan Avenue would be widened to five lanes. These roadways would allow for designated left turns at Highway 41 and the secondary access road intersections. All other east/west roadways are proposed to have only two lanes without designated left turn movements. Both Greensferry and Meyer Roads would be improved to three lanes. All road improvements would include ten feet swales for stormwater runoff and a 10-foot paved bicycle/pedestrian pathway on both sides of the roadways. A 16-foot landscaped median strip would be provided on all north/south and east/west roadways for 300 feet from the intersecting major arterials.
