STH 20 Watermain Relay

3,500 feet of new 12-inch main threaded through a WisDOT reconstruction - including a bore beneath the East Troy Electric Railroad.

Location: East Troy, WI  ·  Client: Village of East Troy  ·  Services: Watermain Design · Construction Oversight · Railroad Coordination

When WisDOT rebuilt STH 20, Lynch designed and oversaw the Village of East Troy's relay of 3,500 linear feet of 12-inch watermain, replacing an undersized 6-inch line inside the highway's construction window. Two night closures and a bored casing under the East Troy Electric Railroad kept the schedule intact with zero missed WisDOT milestones.

Utility Work on a Highway Clock

When WisDOT rebuilt STH 20, the Village seized the window to replace an undersized 6-inch watermain with 3,500 linear feet of 12-inch pipe. Lynch provided design and construction oversight for the relay, synchronized to the highway project's schedule.

The coordination demands were elevated: two nighttime shutdowns of CTH ES limited traffic disruption, and a steel casing pipe was bored beneath the East Troy Electric Railroad - with the railroad coordination that entails. When railroad approvals compressed the timeline, multiple contractor crews worked concurrently to hold schedule.

The Village of East Troy gained 3,500 feet of modern water capacity at a fraction of standalone cost by riding the highway schedule, with no missed WisDOT milestones. Utility relays inside state projects are recurring work for Lynch's municipal engineering team, where schedule discipline is the difference between savings and standstill.
