PROJECT MEMORANDUM - S.P. 0206-55 (T.H. 47) Beginn)ng Ending Description ' Speed limit Reference Reference Point Point 34.256 34.802 .1 mile so~'tl~ of (~SAH 24 to CSAH 81 ' Four-lane rural divided roadway. Proposed Project Listed below are the improvements that have been considered along this section of TH 47. Pavement Preservation l) On TH 47, mill 2 inches and overlay 2 inches from the north end of the TH 10 bridge (Reference Point 20+00.682) to Coolidge Street (Reference Point 22+00.033); a distance of approximately !.4 miles. 2) On TH 47, mill 2inches and overlay 2inches from 700' n°rthof 180th Lane (Reference Point 27+00.775) to County Road 81 in St, Francis (Reference Point 34+00802); a distance of · approximately'6.8 miles. 3) A three-inch thick layer of aggregate will be placed on existing aggregate shoulder~, for the entire length of the project. A drop-off next to the bituminous pavement has formed in many m-cas along the project. Intersection related work (signals and turn laneq) 4) At TH l0 interchange ramp intersections (Reference Point 20+00.662 and 20+00.703); replace the two existing traffic signals. These signals are old, and Metro Traffic has asked that the signals be replaced. This work is currently part of'SP 0206-58. 5) At Pleasant Street (Reference Point 20+00.777) TH 47 is a four-lane undivided urban roadway. In Mn/DOT's 2000 to 2002 Trunk Highway Intersections Database, this intersection ranks 159th out of nearly 4000 intersections, based on crash costs. Metro Traffic has proposed re-striping TH 47 from two though-lanes in each direction, to a lef~ turn-lane and one though-lane in each direction at Pleasant Street. The existing traffic signal will be revised to provide a left turn signal. 6) At the entrance to SCI Recycling Service (west side of TH 47, just north of the railroad tracks; Reference Point 2 I+00), Metro Traffic has proposed constructing a north bound bypass Iane at the SCI Recycling Service entrance (see Figure 7 on page 4). This will allow northbound traffic to bypass vehicles turning into to SCI Recycling Service. Metro Traffic has also proposed adding a raised median between northbound and southbound lanes on either side of the railroad tracks. A - fatal crash occurred When southbound traffic went around the railroad crossing gate by crossing into the northbound lanes, The vehicle was struck by a train. The raised median wilI make it more difficult for vehicles to go around the railroad crossinggates, 7) At McKinley Street (Reference Point 21+00.585), Metro Traffic proposed adding left and right turn-[anes on TH 47, and re-aligning McKinley Street west of'TH 47, so that the though-lanes east and west of the intersection would line-up across from each other. Metro Traffic met with residents in the area in December 2004. The residents wanted a signal at the McKinley Street intersection; however Metro Traffic has determined that the intersection does not meet traffic signal warrants. In January, the Anoka City council voted to delay any work at the intersection, and to do further study. No improvements will be made at McKinley; Street as part of this project. 8) At 142nd Avenue (Reference Point 22+00.420), TH 47 was reconstructed in the late I990s. TH 47 at this intersect/on is a two-lane divided urban roadway with left and right turn-lanes in both directions to 142nd Avenue, and raised center median. Metro Traffic has worked with the City of Ramsey, and decided to prevent traffic on 142nd Avenue from crossing TH 47, or making left- tums onto TH 47. Left turns from TH 47 to 142"a Avenue, and right-tums from 142na Avenue to TH 47 will be permitted. This will be done by extending the raised center median, and adding raised-islands on the 142nd Avenue approaches to TH 47. page 2 File: M/qDOT_DOCSOt415149-v6-PRO,IECT_MEMORANDUM
