Editor, Manteca Bulletin,
I have tried to address this problem with each of the past city managers, city council members, police chiefs, etc., but with no results so  I am going to try again.
I have complained periodically for the past three years now. The issue is large overweight trucks using Airport Way in violation of posted speed limits and weight limits (title 10, section 10.52 mmc) and the inaction of the city to address the problem(s).
I have complained to the city about trucks weighing over 4 tons using Airport Way in the city limits  for the past three  years. Airport  Way was not engineered for large truck traffic. The trucks travel at speeds over the posted speed limit.  Airport  Way between Louise Avenue and Lathrop Road is deteriorating to the point that passing trucks, mostly  traveling  to/from the intermodal facility  on Roth Road as well as trucks from SSI on Louise Ave (in Lathrop) are causing vibration damage to homes that back up to Airport  Way. These trucks are using Manteca as a shortcut; they are not doing any business in the City of Manteca.
There are truck routes available; Louise Avenue  in Lathrop from UP Railroad to 1-5, Roth Road in Lathrop to 1-5, Airport Way from Roth Road to French Camp Rd and French Camp Road between 1-5 and Highway 99. These roads have been designated as truck routes and should be the routes used. 
I have repeatedly asked for enforcement action but have been completely ignored by police officials. The use of Airport  Way by overweight, speeding trucks, in the city limits, has and is causing a quality  of life issue due to noise, road vibration, and safety.
The problem is getting worse due to, among other things, the increased deterioration of Airport Way caused by overweight truck traffic.
