ALLEN COUNTY, Ind. (WANE) -- Dump trucks rolled in every few minutes to get a load of dirt Friday at the Meyer Road jail construction site. The work is going “full steam ahead,” according to one county official after legal delays hampered the project, called the largest construction endeavor Allen County has ever undertaken. The $300 million project is due to be finished in 2027. After a federal judge agreed two years ago with an ACLU lawsuit that the Allen County jail was inhumane due to overcrowding and understaffing, commissioners felt pushed to replace the existing 40-year-old facility downtown. On Friday at the commissioners' weekly legislative meeting, they also approved sharing the engineering costs for a drainage improvement project in the Sunnymede subdivision that shares a boundary with the 140-acre jail. The cost to the county will be $570,000, according to Chris Cloud, the commissioners' chief of staff.  Help in improving decades of drainage problems in that New Haven neighborhood was a promise the commissioners made to the residents, Commissioner Nelson Peter pointed out. “We have started moving dirt and anyone who’s been on that side of Allen County has probably seen a lot of large equipment. As with any construction, you’ve got to get the dirt work taken care of. We’ve got not only earth movers, but we’ve also been dumping a lot of stone to get the ground appropriate, eventually, hopefully in November to start pouring concrete,” Commissioner Therese Beck said Friday after the meeting. Because the groundwork was laid to start immediate construction, even while the lawsuit filed by Meyer Road neighbors in the Indiana Tax Court went through the court system, construction began Oct. 7, Cloud said. He added that the concrete pad was to be poured in mid-November. Brown said the commissioners expect to hold tight to the current timeline which would put the completion date around September 2027, rather than in the summer months of that year, but there are factors such as weather and supply chains that could speed up or slow down progress. “Pauly Jail systems (Pauly Jail Building Co. based in Noblesville ) will prefab all the jail cells,” Brown continued. “If you’re one of the few entities that constructs these kinds of things across the country, you’re in a queue. We’re moving in the right direction right now.”
