Clark County Bridge #95
Clark County Bridge #95 New Bridge Replacement – Wieseka Hill Road over Indian Creek
USI designed the recently constructed Clark County Bridge #95 new bridge replacement, which carries Wieska Hill Road over Indian Creek. Additionally, USI’s construction management team supervised and inspected the construction part-time during critical operations.
Before the improvement project, Wieska Hill Road over Indian Creek featured an unsafe “S” bend curve at the base of a steep hill making it especially hazardous to navigate during inclement weather. The inspection report rated the roadway alignment as “3/10 – Serious,” indicating a vehicular speed decrease to at least 10 miles per hour to safely cross the bridge. Indian Creek is prone to flash flooding through the project area; in turn, caused frequent roadway flooding and the bridge to scour.
The newly constructed, locally funded, Clark County Bridge #95 and road realignment was designed to cost-effectively smooth out the “S” curve, diminish roadway flooding frequency, and reduce potential scouring. The replacement bridge is a durable single-span, reinforced concrete slab with tall abutments built on rock. The wingwalls were extended with MSE walls – creating a more cost effective and innovative approach than similarly used cast-in-place concrete wingwalls.
The roadway realignment required a stream removal and relocation. USI designed, permitted, and helped guide Clark County during the various vital construction elements within this project. From the project onset, USI met with permitting agencies to discuss the project impacts to expedite the permitting process. This meeting was critical to the success of the project; we discovered that Indian Creek is well known haven for archaeological artifacts. Due to this significant information, a historic archeology review was performed early in the design process and kept the project on schedule.
Construction was phased so the new relocated stream was vegetated before the existing stream was removed. Due to the amount of traffic through the area, the new bridge was built while the existing bridge remained open to traffic. During the approach tie in process, a short duration road closure was implemented to minimize disruption to local motorist. This was significantly important to Clark County because the road closure required a long and winding detour route.
USI helped Clark County find a cost-effective resolution to a complex problem. From replacing the bridge and realigning the roadway to stream and tree mitigation — USI went above and beyond to deliver a quality, economical solution for the county.
