- About Us
After 18 months of planning and design, the Highway 36 and Rice Street Interchange Project is under construction. The project includes the replacement of the standard diamond interchange with an offset single-point interchange to improve intersection spacing as well as safety and capacity issues along Rice Street. The Rice Street corridor is being converted from a three-lane section to a four-lane divided section with turn lanes, bike lanes, and sidewalks.
The Rice Street Bridge and the ramp bridges over Highway 36 are tentatively scheduled to be complete by early summer 2011. Work on Rice Street and side streets is tentatively scheduled to be complete in summer 2011. Minor work will continue into fall 2011. The project completion date is October 28, 2011.
January 2010 Open House Held - To provide an opportunity for all interested parties to review the Rice Street/Highway 36 Interchange and Rice Street preferred alternative layout, a public open house was held Wednesday, January 20, 2010 in the Rose Room at the City of Roseville Skating Center.
Based on detailed traffic analysis and public input, the Project Management Team has selected the Offset Single Point Interchange as the preferred alternative to be carried forward for further review in the environmental document The reason for this decision is identified below.
The preferred alternative also includes improvements to the Rice Street corridor (Offset Single Point interchange) from CR B to CR B2 as indicated below:
Stormwater and drainage improvements would be included to achieve watershed standards.
What is the Rice Street/Highway 36 Interchange Study?
Trunk Highway (TH) 36 is an important statewide corridor designated as a principal arterial, high-priority interregional corridor. Rice Street (CSAH 49) is a minor arterial that serves as an important reliever to I-35E. The growth of the general area has resulted in additional traffic and development pressures in the communities along TH 36 and the various north/south roadways serving the trunk highway. This project (S.P. 6212-165) addresses issues at the intersection of TH 36 and Rice Street. It includes the reconstruction of the Highway 36 and Rice Street interchange, and also improvements to Rice Street between County Road B-2 on the north end, and County Road B on the south. The project resides mostly in the city of Roseville, however portions of the project also enter the cities of Maplewood and Little Canada. Currently the project is in the Preliminary Engineering and Environmental Assessment phase, which will conclude in March 2010. There is no funding currently assigned for construction of the project; therefore a construction date has not yet been identified. Ramsey County is currently pursuing funding.
Why is the project necessary?
The purpose of the proposed Rice Street/Highway 36 interchange improvements is to address existing and future safety and operational deficiencies. The need for the project is driven by:
Anticipated increase in traffic volumes on Rice Street from 20,000 vehicles per day to (existing) to 27,200 vehicles per day (2033).
Additional concerns include:
Mn/DOT initiated a brainstorming and internal screening effort to determine the range of feasible interchange concepts that would be reviewed by the Project Management Team. The Mn/DOT process resulted in five unique concepts. The consultant also developed additional concepts, and one of these were included in the initial screening process, for a total of six interchange concepts.
A level of service (LOS) analysis was conducted using year 2033 traffic forecasts to assess traffic capacity and operational characteristics for each of the six interchange concepts. Based on this analysis, three of the concepts were eliminated from further consideration. The remaining three concepts represent more traditional single point and diamond interchange types. These types appear to accommodate the forecast traffic volumes, operate at a high level of service, and present common design features that are understood by drivers. The remaining three interchange concepts included:
Within these three concepts, there are unique design options that were also considered and carried forward for further evaluation. Based on detailed operational analysis and a qualitative screening including such factors as construction cost, right-of-way impacts, and other social and environmental factors, an Offset Single Point interchange was selected as the Preferred Alternative.
