Connecting Regions With High-Capacity Corridors

National and state highways form the backbone of India's economic mobility, linking cities, ports, and industrial hubs. HRP Infra delivers full-lifecycle highway engineering — combining GIS-driven route selection, robust geometric and pavement design, and rigorous construction supervision aligned with NHAI, MoRTH, and IRC frameworks.

From two-lane state highways to multi-lane access-controlled corridors and expressways, our integrated approach optimises alignment, minimises land acquisition, and ensures long-term structural performance under heavy commercial traffic loads.

What We Deliver

Our Highway Service Offerings

Comprehensive consultancy across every phase of national and state highway development.

Route Planning & Alignment

GIS, LiDAR, and DGPS-based corridor identification, terrain analysis, and alternative alignment evaluation to select cost-effective, low-impact highway routes.

Feasibility & DPR

Traffic surveys, demand forecasting, techno-economic feasibility, and detailed project reports prepared to NHAI and MoRTH documentation standards.

Geometric Design

Horizontal and vertical alignment, superelevation, sight distance, interchange and grade-separated junction design as per IRC:73 and IRC:SP:73 norms.

Pavement Design

Flexible (IRC:37) and rigid (IRC:58) pavement design, overlay design, and lifecycle cost analysis for high-volume commercial traffic corridors.

Road Safety Audits

Multi-stage road safety audits from design to post-construction, signage and marking schemes, and crash-barrier design per IRC:SP:88 and IRC:35.

Construction Supervision

Authority Engineer / Independent Engineer services, material testing, quality audits, and milestone-based progress monitoring through to handover.
