PROJECT MEMOtL~.NDU-M - S.P. 0206-55 (T.H. 47) Beginning Endi~ Description .... Spe'ed'li'mi~ Reference Reference Point Point 34,256 34.802 ] ~ mile south of CSAH 24 to C~,~H 81. r.. Four-lane rural divided roadway. Proposed Pro.iect Listed below are the impro~,ements that have been considered along this section of TH 47. Pavement Preservation 1) 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 Sl~eet (Reference Point 22+00.033); a distance of approximately [.4 miles. 2) On TH 47, milt 2inches and overlay 2inches from 700' north of 180~' Lane (Reference Point 27+00.775) to Coun~ Road 8 !. in St. Francis (Reference Point 3z[+00802); a distance of · approximately 6.8 miles. 3) A three-inch thick layer of aggregate will be placed on existing ag~regate shoulders, for the eutire length of the project. ,4. drop-off next tn the bituminous pavement has formed in 'many areas along the project. Inter~vection related work (signals and turn lanes) 4) At TH [0 interchange ramp intersections (Reference ~oint 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 2ffq-00,777) TH 47 ia a four-lane undivided urban roadway, ha Mn/DOT's 2000 to 2002 trunk Highway Intersections Database, this.intersection ranks 159'~ out of nearly 4000 intersections, based on crash costs. Metro Traffic has proposed re-striping TH 47 fi'om two though-lanes in each direction, to a left turn-lane and one though-lane in each direction at Pleasant Street. The existing traffic signal will be revised to provide a reft rum 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 ~ proposed constructing a north bound bypass lane 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 faml crash occurred when southbound traffic went around the railroad crossing gate by crossing into the northbound lanes. The vehifile was struck by a Wain. The raised median will make it more difficult.for vehicles to go around the railroad crossing gates. At McKinley Street (Reference Point 21+00.585), Metro Traffic proposed adding left and right mm-lanes on TH 47, andre-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 h~ 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 fi. wther study. No improvements will l~e made at McKinley Street as part of this project. 8) At I42nd Avenue (Reference Point 22+00.420), TH 47 was reconstructed in the late 1.990s. TH 47 at this intersect/on is a two-lane divided urban roadway with [eft and right tom-lanes in both directions to 142nd Avenue, and raised center median. Metro Traffic has worked with the City of Rarnsey, and decided to prevent'traffic on 142nd Avenue from crossing TH 47, or making left- tums onto TH 4'7. Left tums from TH 47 to 142~a Avenue, and fight-toms from 142'~ Avenue to TH 47 will be permitted. This will be done by extending the raised center median, and adding raised-islands on the [42nd Avenue approaches to TH 47. ' ' page 2 File: MNDOT_DOCS~415149-v6- PROJECT_MEMORAND UM
