by a full diamond interchange. The road has a bituminous surface over a 24- foot wide concrete pavement. The existing bridge over I -35W is a concrete structure that is approximately 30 feet in width. The existing roadway south of the freeway interchange is in fair to poor condition and the underlying concrete joints have caused reflective cracking of the bituminous surface. Right -of -way width is 80 or 100 feet. North of the freeway interchange, Lake Drive is a four -lane divided roadway that was constructed in 2001. This section of roadway is in excellent condition. The northbound I -35W freeway exit and entrance ramps are offset along Lake Drive and need to be realigned to improve intersection safety. The Lake Drive intersections at Town Center Parkway, northbound I -35W ramps, and southbound I -35W ramps are not signalized. 2.2.2 Proposed Improvements Geometric improvements for Lake Drive were first identified in a traffic study conducted by SEH, in response to submittal of the proposed site plan by The Hartford Group. Lake Drive is proposed to be reconstructed from a point approximately 700 feet south of Town Center Parkway to the I -35W freeway bridge. Beginning at the south end, the roadway will be tapered from the existing two -lane section to a four -lane section that includes northbound left and right -turn lanes at the approach to Town Center Parkway. Immediately north of Town Center Parkway, Lake Drive will have 3 southbound lanes (one through lane and two left -turn lanes) and two northbound lanes. One of the northbound lanes will serve exclusively as a right -turn lane to the I -35W northbound entrance ramp. Approaching the I -35W northbound ramps, Lake Drive will have one southbound lane, a large median area, and two northbound lanes. Immediately north of the ramps, Lake Drive will have two southbound lanes (one through lane and one left turn lane) and one northbound lane before tapering down to the width of the existing bridge. Northbound I -35W freeway entrance and exit ramps will be realigned to eliminate the existing intersection offset at Lake Drive. Approximately 150 feet of the exit ramp and 550 feet of the entrance ramp will be realigned. Full- actuated traffic signals will be installed at three intersections: 1. Lake Drive at Town Center Parkway 2. Lake Drive at realigned I -35W northbound ramps 3. Lake Drive at I -35w southbound ramps A permanent signal will be installed at the Town Center Parkway intersection while temporary signals will be installed at the two ramp intersections. To optimize traffic operations, the three signals will be interconnected with an existing signal at the intersection of Lake Drive and Apollo Drive.
