Heading Southbound on Heisley Rd, from Rt. 2, toward Jackson St., all arrows indicate "straight" in the outside bound lane. No indication that the "straight lane" is eliminated until just past "Lincoln Electric Dr.". At this point, the only indication that the "straight lane" has been eliminated is a "small sign" indicating, "right turn only".. for the West bound Jackson St. turning lane. Although, there is an arrow painted on the pavement, it is worn and impossible to see during the recent winter snow/ice covered road. This is a VERY DANGEROUS condition, since many motorists, not familiar with the directions, are suddenly faced with potential ACCIDENTS , by suddenly "cutting in front" of the vehicle already in that lane. This is a very DANGEROUS condition that has existed since the inception of the expanded Heisley Rd., and construction of the overhead railroad bridges. SOLUTION:.....>>>ADDITIONAL SIGNS PLACED FURTHER NORTH ON HEISLEY RD. TO PROVIDE AMPLE WARNING OF MERGING LANES.
