Public Comments from the September 17, 2008 Open House for CSAH 83 The proposed raised median on TH 10 at 149th Lane will prohibit southbound left turns onto Armstrong. Rerouting this traffic to 150th Lane is inconvenient and unsafe. As traffic volumes grow on their highways, Anoka County utilizes access management to maintain safe, efficient traffic flow while providing reasonable access to properties. With Bunker Lake Boulevard less than 1/4 mile away, closure of tho TH 10 median opening at 149th Lane is consistent with the County's access spacing guidelines. Rerouting left tlU11S to the intersection at 150th Lane is consistent with the County's goal of providing reasonable access and their plans to maintain the fire station entrance/150th Lane as a full-access intersection. Regarding the safety of 150th Lane, Anoka County traffic collision data over the last three years studied indicates that no reported accidents occUlTed at the 150th Lane intersection while one accident was reported at the intersection at 149th Lane. Northbolmd site distance at 150th Lane extends through the Alpine Drive intersection and its profile provides a relatively-flat landing as it approaches Armstrong Boulevard. What type of access will be provided to the south leg of Armstrong Boulevard during construction? During the longest stages of the project (Stages 2 and 3), full access will be available to the south leg of AnnstTOng Boulevard. During the first stage ofthe project, the recol1stmction and relocation of the TH 10/CSAH 83 intersection will require that the TEl 10 median be closed for approximately 2-3 weeks. During this time, the south leg of the intersection will have right-inlright-out access and no left turns to or fi.-om this southerly leg will be possible. For northbound Armstrong traffic heading west, a right-turn onto TH 10 and a subsequent U-turn at the next median opening will be necessary. For westbound TH 10 traffic heading south, a U-turn at the median opening west of Atmstrong and a subsequent right-turn onto Armstrong will be necessary. Currently, when a train crosses Armstrong Boulevard, the traffic signal at TH 10 stops Armstrong traffic and allows TH 10 traffic to keep moving parallel to the train. After the train passes, why does southbound Armstrong traffic that has stacked-up have to wait even longer, while the TH 10 traffic gets a green light? MnDOT clUTently has this signal phased so that, after the railroad preemption has concluded, the vehicles in the TH 10 right- and left-turn lanes that had not been allowed to turn north onto Armstrong get precedent over southbound Armstrong traffic. In response to this question, MnDOT reported that they will investigate this situation after the new signal has been installed and the project has been completed. You need to allow (northbound to westbound) left turns onto TH 10 while a train is stopping traffic on TH 10 and Armstrong. During the signal's normal operation, Armstrong traffic acclUnulates on the intersection's north and south legs while the larger traffic volume on TH 10 is proceeds east and west. Ifno trains are crossing, accumulated north-south traffic is then released while TH 10 traffic is stopped. However, because southbound Annstrong traffic will always be restli.cted when a 11'ain is present, the only -170- I: \Engineering\2006 Projects\06-20 Armstrong BoulevardlPublic Comments from the September 17.doc
